     new 43b4ad9  HBASE-22012 Prevent DISABLE quota violation policy from disabling violation
policy
43b4ad9 is described below

commit 43b4ad9e8a50bf25a45bba4469f608c18521aeb0
Author: shardul-cr7 <shardulsingh22@gmail.com>

    HBASE-22012 Prevent DISABLE quota violation policy from disabling violation policy
    
    Space quotas has a feature which intends to avoid enacting a space quota
    violation policy when only a subset of the Regions for that Table have
    reported their space usage (under the assumption that we cannot make an
    informed decision if we do not include all regions in our calculations).
    
    This had the unintended side-effect, when a table is disabled as a part
    of a violation policy, of causing the regions for that table to not be
    reported which disables the violation policy and enables the table.
    
    Need to make sure that when a table is disabled because of a violation
    policy that the code does not automatically move that table out of
    violation because region sizes are not being reported (because those
    regions are not open).
    
    Closes #572
