Admin endpoints - Githubissues

there is some room for improvements but not necessarily in scope of this PR:

slashes at the end of the url don't work
config via environment does not work with multiple databases (we spoke about it)
does it make sense to create and delete databases on a running server? delete the files?
should the db-name be part of the url? this might be more resty
there should be examples in the swagger doc
should q have limit and offset params?
