zhang.lei a1b0c09005 Remove -u root as mysql is executed with root user

As openstack installation guides suggest to run mysql with root shell
user, mysql will not ask for password, so in
controller-install-*.rst "-u root -p" is useless.

Prerequisites

Before you install and configure the Infrastructure Optimization service, you must create a database, service credentials, and API endpoints.

Create the database, complete these steps:
- Use the database access client to connect to the database server as the root user:
```
# mysql
```
- Create the watcher database:
```
CREATE DATABASE watcher CHARACTER SET utf8;
```
- Grant proper access to the watcher database:
```
GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'localhost' \
  IDENTIFIED BY 'WATCHER_DBPASS';
GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'%' \
  IDENTIFIED BY 'WATCHER_DBPASS';
```
  Replace WATCHER_DBPASS with a suitable password.
- Exit the database access client.
```
exit;
```
Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

To create the service credentials, complete these steps:

Create the watcher user:

$ openstack user create --domain default --password-prompt watcher
  User Password:
  Repeat User Password:
  +---------------------+----------------------------------+
  | Field               | Value                            |
  +---------------------+----------------------------------+
  | domain_id           | default                          |
  | enabled             | True                             |
  | id                  | b18ee38e06034b748141beda8fc8bfad |
  | name                | watcher                          |
  | options             | {}                               |
  | password_expires_at | None                             |
  +---------------------+----------------------------------+

Add the admin role to the watcher user:
```
$ openstack role add --project service --user watcher admin
```
Note

This command produces no output.

Create the watcher service entities:

$ openstack service create --name watcher --description "Infrastructure Optimization" infra-optim
  +-------------+----------------------------------+
  | Field       | Value                            |

  | description | Infrastructure Optimization      |
  | enabled     | True                             |
  | id          | d854f6fff0a64f77bda8003c8dedfada |
  | name        | watcher                          |
  | type        | infra-optim                      |
  +-------------+----------------------------------+

Create the Infrastructure Optimization service API endpoints:

$ openstack endpoint create --region RegionOne \
  infra-optim public http://controller:9322
  +-------------+----------------------------------+
  | Field       | Value                            |

  | type        | infra-optim                      |
