Description of problem:

"rhsc-manage-domains" --help gives usage of "engine-manage-domains"


Version-Release number of selected component (if applicable):  Red Hat Storage Console Version: 2.1.0-0.bb9.el6rhs 


How reproducible: Always


Steps to Reproduce:
1. Execute #rhsc-manage-domains --help and see the output
2.
3.

Actual results: It shows reference to "engine-manage-domains". See below:

-----
USAGE:
        engine-manage-domains -action=ACTION [-domain=DOMAIN -provider=PROVIDER -user=USER -passwordFile=PASSWORD_FILE -interactive -configFile=PATH -addPermissions -forceDelete -ldapServers=LDAP_SERVERS] -report
-----


Expected results: If we are re-branding the upstream "engine-manage-domains" as 
"rhsc-manage-domains" in RHS-C, we need to make sure that all references are changed accordingly to avoid any confusion in the users.


Additional info:

Also, the following examples given in the 'help' doesn't seems to work:

Examples:
                -action=add -domain=example.com -user=admin -provider=IPA -passwordFile=/tmp/.pwd
                        Add a domain called example.com, using user admin with ldap server type IPA and read the password from /tmp/.pwd.
                -action=edit -domain=example.com -provider=ActiveDirectory -passwordFile=/tmp/.new_password
                        Edit the domain example.com, using another password file and updated the provider type to Active Directory.
