only clone docs from gh-pages branch if they aren't there

Allow the caller of this script to decide which commit
from the gh-pages branch should be used to build the docs.
This also avoid excessive repeated git clones during development.

Fixing space issues between " and ]

When we are using '[' aka. ``test`` , before the closing ']'
we need to use a space.

Otherwise the commands return with '2' so the "expression" will be a constant
false.

Allow users to configure the CM pipeline interval

The patch allows users to configure the ceilometer pipeline interval.
In localrc, we can add CEILOMETER_PIPELINE_INTERVAL=10 to handle the
pipeline each 10 seconds instead of the default 10 minutes.

the availability of the Ironic service must be set in
the tempest config.

xenapi: enable user to specify FLAT_NETWORK_BRIDGE

install_os_domU.sh failed, if the FLAT_NETWORK_BRIDGE is found in
localrc. As nova looks up the network by either name-label or bridge
name, it makes sense to enable the user to specify this parameter. As an
example, if the user wants to use name-labels to specify networks, and
those name-labels could be used in domU to create bridges:

VM_BRIDGE_OR_NET_NAME="osvmnet"
FLAT_NETWORK_BRIDGE="osvmnet"

In this case, the domU will know only about a name label, so it could be
decoupled from which xapi bridges used.

This change also adds some fixes (missing double quotes).

upload_image.sh should handle file URLs

upload_image.sh doesn't handle correctly file URLs: a file URL works only
if the file is already in the cache.
This patch provides support for file URLs of local files (RFC 1738)

Fix stackforge_libs installation step

When stackforge_libs is enabled, the WSME and Pecan libraries
are checked out from stackforge and installed from source instead of
pip. This change introduces a new function to perform the installation
without attempting to sync the global requirements list, since the
version of setup.py in the global requirements repository breaks the
dependencies for WSME (there is no ipaddr library in python 2, so we
need to install it, but under python 3 where it is part of the stdlib we
cannot include it in the requirements).

Fixes bug 1252488

Make use of STACK_USER instead of relying on USER

Quite easily one ends up calling ./stack.sh in an environment that,
albeit being user "stack" (for example), doesn't quite meet the
expectations of devstack.  The errors that follow can be rather hard to
track down, as the dependency on `USER` is not mentioned.

To remedy this situation, this commit

- uses STACK_USER instead of USER and
- mentions that dependency in the script headers of lib/*

Update vsphere image filename pattern

The vsphere image filename pattern has been updated so that semi-
colons are used to delimit image properties rather than colons,
which are not permitted in Windows filesystems. To support back-
wards compatibility, colons can still be used.
