[feat] full caching for each sync_id session
The CouchDB backend implementation was accessing CouchDB too many times
for the same values. Those values are known inside the same sync_id,
which is the id of current sync session.
This commit adds caching for all redundant calls to Couch inside the
same sync_id for each replica.
Refactoring is still needed, but for now couch.py works normally as if
caching is not present, while sync.py injects the cache as a attribute
to enable it. This needs a simpler implementation.
