[Pulp-list] Simple ping service



Hello,

I have created a very simple ping service that just respond with current timestamp. I use it for my "alive" script. I prefer such a simple service because other services could likely pull some data from database. The ping service should be fast. It also does not require any authentication.

It could return the pulp version rather than current time but I did not find a way to retrieve version. I guess its not stored in the codebase yet.

What you think?
