Deployment doc did not work for non-root user

[Dou Rui Yuan]

Zaqar deployment doc has several wrong places when deploy zaqar using non-root user:

1. File '/etc/systemd/system/zaqaruwsgi.service' should be '/etc/systemd/system/zaqar.uwsgi.service' according to the service start command 'systemctl start zaqar.uwsgi.service'

2. Got Error when service start : open("/var/run/zaqar.pid"): Permission denied, should create and chown for pid file first.

3. Got : ImportError: No module named zaqar_uwsgi, should change workdir to the path '/srv/zaqar' which zaqar_uwsgi.py in.

4. It's better to move zaqar.conf into /etc/zaqar/ instead of /etc/.

5. zaqar.conf miss 'identity_uri' for section keystone_authtoken

    Correct descriptions of install doc

    1. add create pid step
    2. correct service config file name to 'zaqar-uwsgi.service'
    3. move zaqar.conf into /etc/zaqar/
    4. change uwsgi workdir to path '/srv/zaqar'
