Improper usage example in README.rst

[Jeffrey Guan]

Two minor comments:

1. To keep align with openstack common services, it might be better to update the example for creating database and grant privileges from

 69 * Create the database and grant privileges::
 70
 71 $ mysql -u root -p
 72 mysql> CREATE DATABASE mistral;
 73 mysql> USE mistral
 74 mysql> GRANT ALL ON mistral.* TO 'root'@'localhost';

to

 69 * Create the database and grant privileges::
 70
 71 $ mysql -u root -p
 72 mysql> CREATE DATABASE mistral;
 73 mysql> USE mistral
 74 mysql> GRANT ALL PRIVILEGES ON mistral.* TO 'mistral'@'localhost' IDENTIFIED BY 'MISTRAL_DBPASS';
 75 GRANT ALL PRIVILEGES ON mistral.* TO 'mistral'@'%' IDENTIFIED BY 'MISTRAL_DBPASS';

in mistral/README.rst.

2. Improper example for "auth_uri" and "identity_uri" in mistral/README.rst.

It might be better to update from

111 #. Provide valid keystone auth properties::
112
113 [keystone_authtoken]
114 auth_uri = http://<Keystone-host>/identity_v2_admin/v3
115 identity_uri = http://<Keystone-host/identity_v2_admin
116 auth_version = v3
117 admin_user = <user>
118 admin_password = <password>
119 admin_tenant_name = <tenant>

to

111 #. Provide valid keystone auth properties::
112
113 [keystone_authtoken]
114 auth_uri = http://keystone-host:port/v3
115 identity_uri = http://keystone-host:port
116 auth_version = v3
117 admin_user = <user>
118 admin_password = <password>
119 admin_tenant_name = <tenant>
