[Bug 1869620] [NEW] python3-glanceclient emits annoying SyntaxWarning

[Paul Collins]

Public bug reported:

Every time I run something that uses glanceclient, it emits this
annoying warning, which I can't do much about:

/usr/lib/python3/dist-packages/glanceclient/common/http.py:180: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if kwargs.get('cacert', None) is not '':

This could certainly be

  if kwargs.get('cacert', None) != '':

or maybe even

  if kwargs.get('cacert', None):
