In the situation where the flushes take longer than the incoming
rate of writes, the RollupsWriteCache will take every connection
in the database pool and use them forever. Instead of doing that
and taking down satellite availability, bound the number of flush
operations that it will perform and drop incoming writes earlier
to keep memory usage constant.
Adds monitoring events for if any flushes or updates are lost.

Delete satellite order methods and DB tables which aren't used anymore
after we have done a refactoring on the orders to stuck bucket
information in the orders' encrypted metadata.
There are also configuration parameters and a satellite chore that
aren't needed anymore after the orders refactoring.

Currently we risk losing pending bandwidth rollup writes even on a clean
shutdown. This change ensures that all pending writes are actually
written to the db when shutting down the satellite.
