than a type error as it should have.

Enforce ``saml2`` protocol in Apache config

Shibboleth, a SAML2 federation software should only protect urls with
protocol set to ``saml2``. Therefore, <Location> directive in the Apache
config should enfore this, instead of accepting every protocol.
Mind that a vhost should still accept all the protocols.

remove unneeded definitions of Python Source Code Encoding

I think PEP 0263 (http://legacy.python.org/dev/peps/pep-0263/) is
not used anywhere else and so it should be removed when it's not
needed.

Sync service module from oslo-incubator

Previously we synced with oslo-incubator commit hash
caed79d8239679cb74476bb0d9e5011b4fcc39da.

This adds the service module from the same oslo hash.

The service module is required for bug 1157261.

Use code-block for curl examples

The code-block directive wasn't used for literal blocks in the
curl examples document, so they weren't highlighted nicely.

Add v3 curl examples

There were curl examples for v2 APIs, but none for V3. This change
adds some that I've found handy.

Also, added an example of getting the revocation list using the v2
API. This is handy for checking token revocations.

Make sure domains are enabled by default

Domains without an explicit 'enabled' key in the dict will now be
handled in the same way as projects are. This will ensure that
the KVS backend produces the same result as the SQL backend for
assignment.

Add missing docstrings and 1 unittest for LDAP utf-8 fixes

A minimal backport of these accepted master commits:

https://review.openstack.org/#/c/82396/
https://review.openstack.org/#/c/82398/
https://review.openstack.org/#/c/82399/

was done for Icehouse in the following:

https://review.openstack.org/#/c/91883/

In the above backport review it was requested docstrings be added for
some functions and an additional unittest be added. That work was done
for the Icehouse backport and was positively reviewed, at the same it
was requested the those changes be reflected back into master so as
not to lose them going forward. This patch does that, adds the
docstrings and one additional small unittest.
