Promote AcraApplication deprecations to error level

[Luna712]

I know this is really early, but I personally PRed replacements for these to every single repo that used AcraApplication and listed in recloudstream/cs-repos. Therefore to make it less likely something starts using it again, I would prefer to do this earlier now, since it only affects build, not runtime.

If you decide you don't want to yet that is understandable, and this can be closed.

I am still marking this is draft for about another day or two though (maybe a little longer if it takes longer for at least the actively maintained repos to merge my PRs, most already have though)

These are good changes, but I still want at the very least a week of waiting, maybe even a month before marking as errors in builds.

Changes from upstream which force abrupt code changes are very irritating and I really want to lessen that feeling as much as possible. Making pull requests to various repositories to address this is great!

I think the risk of new AcraApplication usage after the deprecation is less than the risk/irritation of abrupt changes, which is why I want to wait so long.

With the now large backlog of pull requests I think this can stay opened while I review them.

That is absolutely fair and makes sense.
