Need to be able to define image_member_quota on glance-api.conf

[David Manchado]

Description
===========
There is no way to change the value for image_member_quota on /etc/glance/glance-api.conf as long as it is not defined in THT or puppet-modules

Steps to reproduce
==================
None

Expected result
===============
Be able to define a value on custom templates file to modify the value for the image_member_quota.
We need to be able to share an image to a large amount of projects and we are hitting the 128 default value.

Actual result
=============
There is no way to define a value for overriding the default value

===========

@David Manchado can you give us an example about the current use case failing with this bug?

[David Manchado (dmanchad)]

Due to internal policy we need to share a private image to a large amount of projects so we cannot make it public.
Not being able to raise that value means that in our particular cases roughly half of the developers cannot consume the images they should use for their daily job.
