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.

This PR introduces functionality for routine deletion of archived orders.
The user may specify an interval at which to run archive cleanup and a TTL for archived items. During each cleanup, all items that have reached the TTL are deleted
This archive cleanup job is combined with the order sender into a new combined orders service
* pkg/process: Fatal show complete error information
Change the general process execution function to not using the sugared
logger for outputting the full error information.
Delete some unreachable code because Zap logger Fatal method calls exit
1 internally.
* storagenode/storagenodedb: Add info to error
Add more information to an error returned due to some data
inconsistency.
* storagenode/orders: Don't use sugared logger
Don't use sugar logger and provide better contextualized error messages
in settle method.
* storagenode/orders: Add some log fields to error msgs
Add some relevant log fields to some logged errors of the sender settle
method.
* satellite/orders: Remove always nil error from debug
Remove an error which as logged in debug level which was always nil and
makes the logic that used this variable clear.
* storagenode/orders: Don't return error Archiving unsent
Don't stop the process which archive unsent orders if some of them
aren't found the DB because it cause the Storage Node to stop with a
fatal error.
* rename pkg/linksharing to linksharing
* rename pkg/httpserver to linksharing/httpserver
* rename pkg/eestream to uplink/eestream
* rename pkg/stream to uplink/stream
* rename pkg/metainfo/kvmetainfo to uplink/metainfo/kvmetainfo
* rename pkg/auth/signing to pkg/signing
* rename pkg/storage to uplink/storage

* rename pkg/certdb to satellite/certdb
* rename pkg/discovery to satellite/discovery
* rename pkg/overlay to satellite/overlay
* rename pkg/datarepair to satellite/repair
What: add monkit.Task to a bunch of functions that are missing it
Why: this will significantly help our instrumentation, data collection, and tracing about what's going on in the network
