Make PIP_GET_PIP_URL configurable via local.conf
The default get_pip url regulary times out when starting devstack
from behind company firewalls. Making this a configureable variable,
user can make use of internal git-pip.py mirrors without modifying
any code.

+# The URL from where the get-pip.py file gets downloaded. If a local
+# get-pip.py mirror is available, PIP_GET_PIP_URL can be set to that
+# mirror in local.conf to avoid download timeouts.
+# Example:
+# PIP_GET_PIP_URL="http://local-server/get-pip.py"
+#
+# Note that if get-pip.py already exists in $FILES this script will
+# not re-download or check for a new version. For example, this is
+# done by openstack-infra diskimage-builder elements as part of image
+# preparation [1]. This prevents any network access, which can be
+# unreliable in CI situations.
