Add purge option to remove plugin CLI
By default, the remove plugin CLI command preserves configuration files. This is so that if a user is upgrading the plugin (which is done by first removing the old version and then installing the new version) they do not lose their configuration file. Yet, there are circumstances where preserving the configuration file is not desired. This commit adds a purge option to the remove plugin CLI command. Relates #24981

After a Java plugin has been removed, you will need to restart the node to

complete the removal process.
|
||||
|
||||
By default, plugin configuration files (if any) are preserved on disk; this is
|
||||
so that configuration is not lost while upgrading a plugin. If you wish to
|
||||
purge the configuration files while removing a plugin, use `-p` or `--purge`.
|
||||
This can option can be used after a plugin is removed to remove any lingering
|
||||
configuration files.
