-----------------------------------------------
We can just add a check in the first line of disable and enable api to see if
the table name is a CATALOG table. If so just throw error.
> Disabling of Catalog tables should not be allowed

> HBaseAdmin#disableTable() when called with META or ROOT table, it will pass
> the disable instruction to Master and table is actually getting disabled.
> Later this API call will fail as there is a call to
> HBaseAdmin#isTableDisabled() which is having a check like
> isLegalTableName(tableName).So this call makes the catalog table to be in
> disabled state.
> We can have same kind of isLegalTableName(tableName) checks in disableTable()
> and enableTable() APIs
