Combine store.writeLimit and store.writeOrder into
store.writeLimitAndOrder, which only requires a single call to
file.Write(). This simplifies code, but it also reduces the likelihood
of multiple calls to Write() increasing the likelihood of file
corruption.
Also combine the corresponding readLimit/readOrder functions for
consistency.

We only need to lock aquire mutexes inside ListUnsentBySatellite when we
want to determine whether a file has an active enqueue in progress.
On some nodes, ListUnsentBySatellite can take a particularly long time, having
undesired side-effects, so if we can minimize locking time, those nodes
will be better off.
Also, lock archive mu during ListUnsentBySatellite so files cannot be
archived and listed at the same time.

If we see an UnexpectedEOF error when attempting to read orders, return
the orders we have been able to read successfully and do not return an
error. This behavior ensures that the storagenode orders service
attempts to archive corrupted files and does not retry them repeatedly
and get stuck.

Additionally, this PR changes NewNodeFraction devDefault and testplanet config from 0.05 to 1.
This is because many tests relied on selecting nodes that were reputable based on audit and uptime
counts of 0, in effect, selecting new nodes as reputable ones.
However, since reputation is now indicated by a vetted_at db field that is explicitly set
rather than implied by audit and uptime counts, it would be more complicated to try to
update all of the nodes' reputations before selecting nodes for tests.
Now we just allow all test nodes to be new if needed.

When we call ordersStore.BeginEnqueue, the unsent orders file for that
satellite and hour is prevented from being sent. It is freed when the
commit callback returned by BeginEnqueue is used. This change ensures
that we always call the commit callback, even when we have an empty
order or an order with Amount <= 0.

This change accomplishes multiple things:
1. Instead of having a max in flight time, which means
we effectively have a minimum bandwidth for uploads
and downloads, we keep track of what windows have
active requests happening in them.
2. We don't double check when we save the order to see if it
is too old: by then, it's too late. A malicious uplink
could just submit orders outside of the grace window and
receive all the data, but the node would just not commit
it, so the uplink gets free traffic. Because the endpoints
also check for the order being too old, this would be a
very tight race that depends on knowledge of the node system
clock, but best to not have the race exist. Instead, we piggy
back off of the in flight tracking and do the check when
we start to handle the order, and commit at the end.
3. Change the functions that send orders and list unsent
orders to accept a time at which that operation is
happening. This way, in tests, we can pretend we're
listing or sending far into the future after the windows
are available to send, rather than exposing test functions
to modify internal state about the grace period to get
the desired effect. This brings tests closer to actual
usage in production.
4. Change the calculation for if an order is allowed to be
enqueued due to the grace period to just look at the
order creation time, rather than some computation involving
the window it will be in. In this way, you can easily
answer the question of "will this order be accepted?" by
asking "is it older than X?" where X is the grace period.
5. Increases the frequency we check to send up orders to once
every 5 minutes instead of once every hour because we already
have hour-long buffering due to the windows. This decreases
the maximum latency that an order will be reported back to
the satellite by 55 minutes.

On run, write the storage directory verification file.
Every time the node runs it will write the file even if it already exists.
The reason we do this is because if the verification file is missing, the SN
doesn't know whether it is an incorrect directory, or it simply hasn't written
the file yet, and we want to keep nodes running without needing operator intervention.
Once this change has been a part of the minimum version for several releases,
we will move the file creation from the run command to the setup
command. Run will only verify its existence.

Sometimes SNOs fail to properly configure or lose connection to their storage directory
which can result in DQ. This causes unnecessary repair and is unfortunate for all parties.
This change introduces the creation of a special file in the storage directory at runtime
containing the node ID. While the storage node runs, it periodically verifies that it can
find said file with the correct contents in the correct location. If not, the node will
shut down with an error message.
This change will solve the issue of nodes losing access to the storage directory, but it will not
solve the issue of nodes pointing to the wrong directory, as the identifying file is created each
time the node starts up. After this change has been the minimum version for a few releases, we will
remove the creation of the directory-identifying file from the storage node run command and add it
to the setup command.

* Add all new orders to the orders filestore instead of the database.
* Submit orders from the filestore to the new satellite SettleWindow
endpoint.
The orders filestore will eventually replace the orders DB completely.
For now, we will still be checking the orders DB and submitting those
orders if they exist. In a later release, we will completely remove the
orders DB, but we need both the DB and filestore for the transitionary
period.

We only sync free disk and available space, if necessary, on startup. If the
SNs disk fills up with non-storj data, we will not know about it when reporting
available space to the satellite.
Solution: whenever we check the node's capacity, double check free disk.
If free disk < than expected available space, return free disk.

"The calculation of per object fees is based on a standard 720-hour month."
On most years, the average value is 730 (365*24/12), except leap years.
However, we want to have ours be 720 (30*24) so its lines up with days.

When an uplink or repair work finishes uploading a piece to a
storagenode, it has no reason to wait another round trip after the piece
is committed to gracefully close the connection - in many (most?) cases,
the connection is simply canceled once the upload is complete. This has
the unintended side effect of producing a lot of "piece canceled" logs
and metrics on the storagenode side, when the reality is that the piece
uploads were successful, and not really canceled. This commit fixes
that.
