WIP feat(templates): custom event templates in S3

[mwangggg]

fixes: #13

[andrewazores]

Reopen a new PR from your feature branch please @mwangggg . You might need to re-fork the repository, so be careful about that so you don't lose your feature branch. I have to do something similar so I can let you know what I end up doing to get the commits carried over, but I expect I'll just end up exporting them as patches and re-importing them to the new fork/clone.

Actually I think the easiest quick fix will look like this:

$ cd cryostat3
$ git checkout my-feature-branch
$ git fetch upstream
$ git rebase upstream/main
$ git ps -u upstream my-feature-branch
$ # open a new PR between upstream/main and upstream/my-feature-branch

After that PR is merged you can re-fork and re-clone your copy of the repository. I don't think there is any better way to re-associate the existing fork with the original upstream repository unfortunately.
