-----------------------------------------------------------------
Patch adds two new configuration options, set to current default behavior, and
documents them in hbase-defaults.xml. New unit test.
{{hbase.coprocessor.enabled}} controls globally if any coprocessors will be
loaded. Set to "false" to disable. Defaults to "true".
{{hbase.coprocessor.user.enabled}} controls if any user (aka table)
coprocessors will be loaded. Set to "false" to disable. Defaults to "true".
I use "user" rather than "table" following naming convention of other
coprocessor related configuration keys.
While "hbase.coprocessor.enabled" would be included in the site file along with
any system coprocessor specifications, it is a useful global toggle as
described, and will override any other settings if the site file happens to be
assembled from fragments.
