Fixes: bug #1182037
Allow disabling ssl compression for glance client

Add a new parameter 'glance_api_ssl_compression' which allows
disabling ssl layer compression negotiation for glance requests.

This may improve data throughput, eg when high network bandwidth is
available and you are using already compressed image formats such as
qcow2 .

Addresses bug 1189903.
