Description

In QuotaSettings，the method of sizeToString reserved integer. But, this is not very accurate.

hbase(main):001:0> set_quota TYPE => SPACE, TABLE => 't1', LIMIT => '2000G', POLICY => NO_INSERTS

hbase(main):002:0> list_quotas
OWNER                                    QUOTAS                                                                                                              
 TABLE => t1                             TYPE => SPACE, TABLE => t1, LIMIT => 1T, VIOLATION_POLICY => NO_INSERTS

after patch：

hbase(main):001:0> set_quota TYPE => SPACE, TABLE => 't1', LIMIT => '2000G', POLICY => NO_INSERTS

hbase(main):002:0> list_quotas
OWNER                                    QUOTAS                                                                                                              
TABLE => t1                             TYPE => SPACE, TABLE => t1, LIMIT => 1.95T, VIOLATION_POLICY => NO_INSERTS
