Tomasz Grabiec eb496b5eae Merge "Allow changing configuration at runtime" from Avi 
This patchset allows changing the configuration at runtime, The user
triggers this by editing the configuration file normally, then
signalling the database with SIGHUP (as is traditional).

The implementation is somewhat complicated due the need to store
non-atomic mutable state per-shard and to synchronize the values in
all shards. This is somewhat similar to Seastar's sharded<>, but that
cannot be used since the configuration is read before Seastar is
initialized (due to the need to read command-line options).

Tests: unit (dev, debug), manual test with extra prints (dev)

Ref #2689
Fixes #2517.
