When removing a plugin, removed tables are not removed from remote pollers #4617
Description
Describe the bug
When uninstalling a plugin, if there are tables created on the Remote Data collector, cacti does not take care to remove those plugin tables thus causing the plugin tables to remain.
This issue can not be solved at one time as many Cacti plugins simply perform a db_execute('DROP TABLE blah');. So, this issue must be fully corrected through the incorporation of a plugin function for people who do not use the standard table creation API, plus augmenting the plugin api to remove remote tables.
Expected behavior
More consistent behavior of the plugin API.
