ran this with `go test -count=1000` and it passed all of them.
- we add a closed channel so that we can select on it with
context cancellation.
- we put a once in so we only close the channel once.
- every time the queue/running state changes, we have to broadcast
because we may want to wake up N pending Wait calls or other
concurrent workers.
- because we broadcast, we don't need to do the polling in Wait
anymore.
- ensure Run doesn't start multiple times so that we don't have
to worry about concurrent Close with multiple Runs.
- hold the lock while we start workers so that a concurrent Close
with Run can't decide that there's nothing started and exit
and then have Run start things.
- make sure to poll the closed/context channels through loops
or at the start of Run calls in case Close happens first.
- these polls should be under a mutex because they have a default
case which makes it possible to schedule such that Close hasn't
executed the channel close so it starts more work.
- cancel a local Run context when it's going to exit to make sure
that any retainPieces calls have a canceled context.
- hopefully enough comments to both check my work and help readers
digest what's going on.

* concurrency fixes again
- forgot to update the gc test to use the old Wait api.
- we need to drop the lock while we wait for the workers
to exit, because they may be blocked on the condition
variable
- additionally, we need to broadcast when we close the
signal channel because the state changed: they want
to wake up and exit.

The call to monkit for functions which mostly run from the beginning to
the end of the satellite process must be done because it only causes a
little overhead.
Creates a new chore, dbcleanup, which can be used for routine deletion of items from the satellite database and adds functionality for deletion of expired serial numbers

What: this change makes sure the count of segments is not encrypted.
Why: having the segment count encrypted just makes things hard for no reason - a satellite operator can figure out how many segments an object has by looking at the other segments in the database. but if a user has access but has lost their encryption key, they now can't clean up or delete old segments because they can't know how many there are without just guessing until they get errors. :(
Backwards compatibility: clients will still understand old pointers and will still write old pointers. at some point in the future perhaps we can do a migration for remaining old pointers so we can delete the old code.
Please describe the tests: covered by existing tests
Please describe the performance impact: none
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
This way the design doc process is directly visible when browsing the doc/design folder in the GitHub Web UI. As the number of docs grows it would be harder to find the doc with the design process.
