discover: Handle plugin install request
Handle "_PLUGIN_INSTALL" requests from clients. Calling the pb-plugin
script from pb-discover ensures different clients don't trip over each
other. Successfully installed plugins are automatically communicated
back to clients once pb-plugin sends a 'plugin' user event.
