use author name to name environments

[alrocar]

Closes #22

• CI_MERGE_REQUEST_IID cannot be used as part of the Environment name, since it's only provided in MR creation, so wen merging / closing there's no reference to it.
• Using CI_COMMIT_AUTHOR which might be available at merge time.
• This requires the clean up rule to update to run when the MR is merged.

- &cli_telemetry_cleanup_rule
    if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

• I haven't found an easy way to run a pipeline in GitLab on MR close, so environments won't be deleted when a MR is closed yet.

This has the problem an author can only have a single environment for all their PRs
