Description

Space Quota: Policy state is getting changed from disable to Observance after sometime automatically.

Steps:

1: Create a table with space quota policy as Disable
2: Put some data so that table state is in space quota violation
3: So observe that table state is in violation
4: Now wait for some time
5: Observe that after some time table state is changing to to Observance however table is still disabled

edit (elserj): The table is automatically moved back from the violation state because of the code added that tried to ride over RITs. When a Region is not online (whether normally or abnormally), the RegionSizeReports are not sent from RS to Master. Eventually, enough Regions are not reported which dips below the acceptable threshold and we automatically move the table back to the "acceptable" space quota state (not in violation). We could skip this failsafe when we're checking for a quota that has the DisableTable violation policy.
