Environment variables not set for Identity V3 on openrc

[Thiago Paiva Brito]

For some operations on openstackclient, some environment variables are needed but not set on openrc, generating some erros on keystone such as:

ERROR: openstack Authentication failure: Expecting to find domain in project - the server could not comply with the requet since it is either malformed or otherwise incorrect. The client is assumed to be in error.

ERROR: openstack Authentication failure: Expecting to find domain in user - the server could not comply with the requet since it is either malformed or otherwise incorrect. The client is assumed to be in error.

    Set user/project domain ID when using keystone v3

    Change I24546f02067ea23d088d383b85e3a78d7b43f165 aimed to use
    keystone v3 as default in devstack. The change was later reverted in
    Ia792b23119c00089542ba08879dca1c29dc80945 because it broke some
    projects.
    This patch contains a small portion of the first change to set the
    environment variables $OS_USER_DOMAIN_ID and $OS_PROJECT_DOMAIN_ID in
    openrc, so that users don't have to set them manually when using
    keystone v3.
