ASTERIXDB-1302 ASTERIXDB-1301 Fix Socket Feed Connection

A bug causes a read lock to never be released when a feed is
connected with "wait-for-completion" set to false. The bug
was fixed and a test case was added.
Another bug was causing the socket feed to not receive
connections correctly. The bug was fixed and a test case
was added.
Additionally, this change ensures that adapters have absolute
partitions to ensure consistency with regards to feed log
manager.
