Split reading of versioninfo out into a method

Make the read_versioninfo to match write_versioninfo.

Additionally, there is an edge case where if the code is installed from a
github zipball, versioning info is missing. Now that we're using this,
there should be virtual no instances where a zipball will be easier or
less cost than an sdist created tarball, all of which should be public and
accessible, but during the transition, we need to account for the codepath.

Switch CLI to support underscores and dashes.

Update the glanceclient CLI to support both underscores and dashes.

Dashes are prefered and show up in help.

This will hopefully keep the CLI more consistent with the other
OpenStack client projects like Nova, Swift, Keystone in addition to the
old Glance client which all seem to prefer underscores to dashes.

Fixes LP Bug #1018467.

Allow image filtering by custom properties

sub-dictionary inside of the 'filters' keyword argumen to
ImageManager.list(). The same functionality can be used through
the CLI through the use of one or more'--property-filter' options.
