about sub-packages that aren't really packages.

(ipsec) remove ipsec_force_reload, replace with ipsec_configured_on_interface() to check if a tunnel is configured before reloading ipsec

(ui) add modal form in legacy template to signal the user about pending service action (stop,start,restart)

(mvc) remove incomplete error handling, was superseded https://github.com/opnsense/core/commit/22701ee038722408a8d21916dbb6ee13023a39dd#diff-755c67cb284868a802a88a873c75038c closes https://github.com/opnsense/core/issues/1234

The current issue is you can't actually restart ipsec without disabling and enabling the service, which is odd and confusing.

Convert actions to configd template and change service registration.

Since plugins are now tied to the heartbeat of the system itself,
it makes sense to split out hardcoded base functionality into
their pluggable counterparts.  Start with the candidates that
already have a plugin file.
