- refactor tracing api to take tracer
from library user. Now there is a trait
for Tracer and sbroad does really know
what tracer is being passed
- All tracing tables were moved out to Picodata
- remove tracing from cartridge:
as it is not used and no need to
maintain it

- add support for queries that use
union all operator with global tables
- for the case when global table is
used against sharded table, the global
table is materialized only on single
storage, on all other storages the
global child of union all is not
materialized
