This commit updates the Memcached chart to allow use with images other than Stackanetes, define ImagePullPolicy, and provide config params in the values.yaml.
* Made values.yaml consistent throughout charts. Removed any globals
references in subcharts as these are difficult to override. Only
ports should be in globals to build URLs which can come as part
of a future commit. The hostname endpoint aspect of a service
will come from openstack-base/_hosts.tpl and the port
would come from the chart itself as a global so other charts
can reference the port to build a complete URL. Putting the
hostnames themselves as globals in individual charts makes it
difficult to make a sweeping top level FQDN change.
* Cleaned up yaml requirements and incorporated a new _common.tpl
that is distributed to all charts to allow common endpoint naming
while still retaining the ability to install individual charts.
* Fixed keystone URL generation during bootstrap as a correct
URL is critical given keystone uses this to construct all
subsequent URLs in the request. Also allow controlling the
default endpoint version and scheme.
* Added missing NAMESPACE declaration to keystone deployment
as this is required for entrypoint to discover resources
not in the 'default' namespace.
* Refactored all nodeSelector values to be consistent throughout
all charts
