EZP-28243: Purge type using service id does not work

[vidarl]

Issue: https://jira.ez.no/browse/EZP-28243

1. Fixes so it is possible to use this setting as documented in semantic config help text.
2. Make it possible to add plugin system for ezplatform-http-cache in order to add Fasly support: EZEE-1780: Plugin support ezplatform-http-cache#19

So, may I just remove the offended test which complains since we no longer throws exception on unknown purge_types ( this is instead done by ezplatform-http-cache)

Do you need this on older releases as well? (thinking cases where people don't use ezplatform-http-cache also), or do we aim to require ezplatform-http-cache? (ok with me)

EDIT: We also need an JIRA issue covering this change and the change in ezplatform-http-cache

So, may I just remove the offended test which complains since we no longer throws exception on unknown purge_types

If we go with this, then yes. But ideally we should somehow still throw for people not using ezplatform-http-cache

I basically need this in every version where we are going to support fastly.... Fastly support will require ezplatform-http-cache
Update : we'll need this for 2.0.0 and 1.13.0

So, this is heading for 1.13.0 where ezplatform-http-cache is going to be enabled by default.
Should I still write a check if the ezplatform-http-cache bundle is installed?

Actually v1.12.1 and up, ezplatform-http-cache was enabled by default in 1.12

We should merge #2123 so you can run composer fix-cs before pushing ;)

[vidarl]

hehe. I am not against #2123....

Github won't have me review and approve this PR as I created it.
But I do approve your commits AR...

My commits should be removed before merged though

we always squash now by default, and when not we rebase :)
