stack.sh fails for Cisco plugin with missing cisco_plugins.ini error

When the Cisco Nexus monolithic plugin is configured in the localrc,
stack.sh fails with the error message:
     sed: can't read /etc/neutron/plugins/cisco/cisco_plugins.ini:
          No such file or directory

This failure was introduced with the merge of change set 76992
(bug #1285884). Change set 76992 removed the copying of
Q_PLUGIN_EXTRA_CONF_FILES from the neutron project area to directories
under /etc/neutron. This copy from neutron to /etc is required by the
Cisco Nexus monolithic plugin, since this plugin follows the original
model for generating extra config files based on localrc settings:
 - Copy default config file(s) from neutron project to /etc using
   a relative path (relative to neutron and relative to /)
 - Modify the copies of the config file(s) using localrc settings
 - Add a --config-file command line setting for neutron server which
   points to the modified config file(s) under /etc

The fix is to add the copying of the default versions of the extra
config files from neutron to /etc into the cisco devstack script.

Fix logging for keystone under mod_wsgi

When Keystone is configured under mod_wsgi, Keystone configuration 
requires debugging to be enabled as the debug flag cannot be passed
via cli arguments.

Because Apache 2.2 (default for a number of distributions) does not 
support passing an explicit format to the ErrorLog, Keystone under 
mod_wsgi ends up with duplicated timestamps in the Keystone log. 
This patchset eliminates the %(asctime) and %(msecs) substitution 
targets from the log format options when Keystone is configured 
under mod_wsgi.

on IPv6 endpoint, making imporrible for a node to reach TFTP.
This patch forces TFTP to listen on IPv4 endpoint by modifying
Xinet.d template.

Add an option in lib/swift to increase max_header_size

With the increasing number of entries in the service_catalog header,
some projects will have a header bigger than 8192 and Swift cannot
handle headers of this size. Solum is the first one to have this issue

As a temporary hack to fix Solum's gate, we are increasing
the value of the max_header_size parameter in our "lib" script.

This patch makes this settings global to all projects using devstack,
so that in a near future, if a project has a service_catalog header
bigger than 8192, it doesn't have the same problems we had.

Closes bug 1316585

Use public gateway for Trove if neutron is enabled

Fix Trove to use the PUBLIC_NETWORK_GATEWAY if neutron is enabled.
This is needed since in this case the guestagent is able to reach
the devstack host only via the public PUBLIC_NETWORK_GATEWAY and
not via the private NETWORK_GATEWAY.

Fix incorrect comparisions

The files changed in this commit had incorrect bash syntax in that they were
assigning variables (=) instead of checking if they were equal (==). The
incorrect checks were preventing the configuration of VLANs with the Neutron
ML2 plugin.
