Cinder cannot use glance's ssl_compression feature

[Stuart McLaren]

The glance client allows disabling ssl_compression.
The option to do this should be added to cinder as it can provide a performance boost.

    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.
