form.

Make the tox docs env build the docs

The tools/build_docs script builds the docs for devstack. Use it.

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.

Merge "Cleanup create_accounts functions"
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.
