Ian Wienand 7c4ce9edba Check for new versions of get-pip.py
People can leave their devstack installs around for a long time, and
in the mean time new versions of pip can be released.

The current check does not download a new version if an old one
exists.  We want to check for new versions, but we also don't want the
gate jobs trying this sometimes unreliable fetch.

So add a flag-file that tells devstack if it downloaded get-pip.py
originally.  If so, on each run check for a new version using curl's
"-z" flag to request only files modified since the file's timestamp.
