Which issue this PR fixes
Special notes for your reviewer
Until the exporter supports reading passwords from a file, we are limited to choose out of two solutions:
MONGODB_URIautomatically from the target list BUT share the same username/passwordMONGODB_URIbut also manage the serviceMonitor list separatelyI don't really know what's the best solution, open for suggestions! I went for the first solution which matches my use case but if you think the other option is better for most people, we can rethink the logic.
