[ASTERIXDB-2049][ING] Fix hang in Start Feed
- user model changes: no
- storage format changes: no
- interface changes: no
details:
- The hang is caused by one runtime finishing and unregistering
before another runtime registers. When that happens, the number
of registered runtimes never reaches the total number of runtimes
and so the start feed statement doesn't complete.
- To avoid the situation described above, we use different counters
for registration and deregistration. Since deregistration count
is now kept in another variable, the registrations will either
reach the expected count or a failure will happen and both
cases completes the start feed request.
