Yi Mei updated HBASE-21783:
---------------------------
Description:
Currently, all types of rpc throttle quota (include region server, namespace,
table and user quota) are hard limit, which means once requests exceed the
amount, they will be throttled.
In some situation, user use out of all their own quotas but region server
still has available quota because other users don't consume at the same time,
in this case, we can allow user consume additional quota. So add a switch to
enable or disable other quotas(except region server quota) exceed.

In some situation, user use out of all their own quotas but region server still
has available quota because other users don't consume at the same time, in this
case, we can allow user consume additional quota. So add a configuration named
ALLOW_EXCEED to meet this requirement when set region server quota.
Summary: Support exceed user/table/ns throttle quota if region server
has available quota (was: Support allow exceed user/table/ns rpc throttle
quota if region server has available quota)
> Support exceed user/table/ns throttle quota if region server has available
> quota
