Should be 'db purge' be removed?

[tonyespy]

I'd like to see some discussion as whether or not the inclusion of the 'db purge' command is appropriate for edgex-cli. Most, if not all of the other commands exercise EdgeX's REST APIs.

I see that the command implements a "do you really want to do this check", which is great, however I would feel more comfortable with pointing someone to the actual db tools (e.g. redis-cli).

Maybe this could be discussed at an upcoming Core WG meeting?

The initial idea was to keep the client unaware of the underlying implementation - unaware of what is the used database and still test most of the Delete exported apis . But better is to have a discussion about it.
