Add a version endpoint to SQLMap API #4204

I need to execute a client application on many machines and need a way to make sure the sqlmapapi.py server is the correct version before using some of the options (that have changed between versions).

Describe the solution you'd like

Please add a /admin/version endpoint that returns the version of SQLMap installed.
