added a version diff test

added an abuse-c test to highlight a bug
Added integration tests for rebuilding the indexes, and last table pkey and object.
Pause and resume index rebuild operation.
Removed redundant ANY value from mntner table.
Do not allow reserved words in object name (only mntner attributes for now)
Improved object sanitization integration tests.
First rebuild primary key indexes, then rebuild other indexes (per object type).
Fixed rebuild inet_rtr indexes - don't delete the inet_rtr index from the IndexWithLocalAs strategy, it is updated/deleted in the IndexWithValue already.
