devstack should put admin_tenant_id in tempest.conf file while setup

Some of the test cases in tempest related to quota use
admin_tenant_name, ideally it should use admin_tenant_id.
As tempest.conf file does not contains admin_tenant_id
it should also be updated. tempest.conf file is generated
by devstack while setup of openstack, changes should be made
in devstack so as to put admin_tenant_id in tempest conf file.

Wait for OVS to reconfigure when creating PUBLIC_BRIDGE

The '--no-wait' flag will not wait for ovs-vswitchd to reconfigure after
changes have been made to the database. This causes a race condition as
the bridge may or may not be up when 'ip addr flush dev $PUBLIC_BRIDGE' is
called. This commit removes the '--no-wait' flag which is safe as the
openvswitch services are already started earlier in stack.sh

Cut the heat flavor

1024Mb memory is too much for single instance.
approximately 4 GiB memory used even without a booted VM.

The heat auto-scaling scenario needs to boot 3 VM
(currently disabled), if any other test running in parallel
and boots up a vm it would easily can cause OOM an
issue.

The heat-slow job can work with 128 MiB instance memory,
but this change reduces it just to 512 MiB (safer for the guest),
and enough to avoid OOM issues on the host,
and let us to heve more vm at the same time.

The m1.tiny flavor is not good because now it has a hard coded
1 GiB disk limit and the f20 image requires 2 GiB.
Setting the disk size to '0' -> automatically use the virtual size
of the image.

Using multiple cores does not really helps in boot time :(,
but it might cause higher host load. (More locking)
Reducing the core number to 1.

Use identity_uri instead of auth fragments

auth_token middleware now accepts a standard URL string as the parameter
identity_uri instead of specifying protocol etc individually. Change the
services over to use this.

Also changes over some other places in which the auth fragments are used
individually to the new variables and fixes up some misconfigurations of
auth_token.

identity_uri option was release in keystoneclient 0.8.0

Merge "Support option for Keystone PKIZ token provider"
Fix unsubstituted filename creation

Since merge_config_file() tries to create an unsubstituted config file,
stack.sh fails due to permission denied in the file creation when you
use '[[post-config|/$Q_PLUGIN_CONF_FILE]]' and the file does not exist.

This patch deletes unnecessary 'touch' command, because the file will
be made by 'iniset' function in the next command line with evaled
string from 'configfile'.

This patch also fixes merge_config_group() to use evaled 'configfile'
when it checks the directory of the config file exists.
