Strictness!

Added tier parameter to plugin RPC target BucketId

Changed sbroad vshard related traits and it's capabilities
about working with several vshard groups

Move vshard related fields from _pico_property to _pico_tier
and adapt it in governor algorithm

This moves most of the logic from the supervisor process which helps
with a number of problems with the main_cord stuff. For example in a
following commit the context will only be parsed in tarantool::main_cb
which means config parameters aren't accessible in supervisor.

This also moves us towards getting rid of the supervisor process in the
future.

This reverts commit d7e93cfc.
