Cleanup create_accounts functions

lib/nova and lib/ceilometer had function calls not in the desired
form.

Set Glance default_store to rbd in [glance_store]

Glance is moving from [DEFAULT] to [glance_store] for this option.
Since lib/glance sets both, let's also set it in both places for now.

Failing to do this causes g-api to fail to start with error:
"Store for scheme swift not found"

local.conf processing doesn't handle '=' in values

When attempting to add a libvirt section with a volume_drivers entry
to $NOVA_CONF, via a post-config block in the local.conf file, I
encountered problems; the value for this attribute takes the form

    driver=python.import.path.to.driver

but the value actually populated in the $NOVA_CONF was truncated at the
equals.

Taking the iscsi driver setting specified in the official nova.conf
documentation as an example, if I have the following in my local.conf
file:

[[post-config|$NOVA_CONF]]
[libvirt]
volume_drivers = iscsi=nova.virt.libvirt.volume.LibvirtISCSIVolumeDriver

I will see that the generated $NOVA_CONF has the following:

[libvirt]
volume_driver = iscsi

This occurs because the existing handling for a post-config setion, as
implemented in merge_config_file(), splits the line on the equals sign,
and then uses the first and seconds elements of the resulting array as
attribute name and value respectively.

However when an equals occurs as part of the value this results in the
value being truncated at the first equals in the value.

The fix I've implemented, based upon review feedback, extracts the
contents of $0 before the first equals as the attr name, and extracts
the remainder after the equals as the value. Then it strips the leading
and trailing whitespaces from both as appropriate.

I've also added test5 to tests/test_config.sh to test for, and verify,
correct operation when this scenario is encountered.  Similarly I've
added test6 to ensure that trailing spaces in values are stripped
correctly.

Closes-Bug: #1374482
Allow multi-line config items in meta-section of local.conf

It would behave such as the contents from each meta-section in
local.conf is copied to the destination files. One exception is the multiline
options not grouped together. In that case, the contents will be grouped
together in its destination config file.

Check tests/test_config.sh for examples.

Revert "Allow multi-line config items in meta-section of local.conf"

This reverts commit 6ff21acf4c4d4ef08bbef419ba582cade4da8da7.

This commit has broken config options with colons in them.
The following is a sample configuration that no longer works:

[[post-config|/etc/neutron/plugins/ml2/ml2_conf.ini]]
[restproxy]
server_ssl=False
servers=10.211.1.9:80
server_ssl=False

With the above config and the code present that this reverts,
the 'servers' option will come out blank.

Move the doc paths to match other repos

In order to build in the Infra system, we'd like to be able to reuse the
existing doc build macros. To support that, move docs/source to
doc/source and docs/html to doc/build/html.
