oem-ibm: Add user password error status codes (ibm-openbmc#37)

This commit adds the new and generic user password error status
codes for the following scenarios:

1. Password authentication status
2. Password change status
3. Admin operation status

Example use case:
If host passes the username and password credentials to the BMC, it
could support below requirements through any password validation
mechanism (Ex: PAM module)
1. Password authentication
2. Password change if the password has been expired
