Allow customized SMS message without surrounding "Grafana OnCall" text

[suess-ecbm]

Currently SMS are not customizable except for a string in the middle of the fixed message:

You are invited to check an incident #515 with title "This is a test title" in Grafana OnCall organization: "this is a test organization", alert channel: Grafana Alerting - Grafana Alerting, alerts registered: 1, https://thisisatestorganization.grafana.net/a/grafana-oncall-app/?page=incident&id=I3H1WHSAJ8HWF Your Grafana OnCall <3

The users on our end do not universally speak English, nor do they interface with Grafana OnCall directly.

Therefore we would like to be able to change the whole message content without surrounding fixed references to Grafana Oncall, links and the ascii heart.

The current sms renderer could be changed to leave out that additional fixed text.

Feel free to contribute the change!

My opinion is that we still should have some unified prefix for all SMS to avoid system misuse. Smth like "Grafana OnCall alert:"

so it looks like there was a PR with a solution in https://github.com/grafana/oncall/pull/537, but it looks like it was closed stale by @vadimkerr after input from @Matvey-Kuk so what is the status of this?

@yokhahn if you would like to move this PR forward, I could suggest re-opening it and running through a review.

I've left some questions on the PR, so that I can understand what would need to be changed... the comments over there sort of left me with a lack of understanding of what would actually be needed to be changed.
