Support target server dirs modified by environment

The server migration fails if user changes the target server's standalone/domain base or config directory names, i.e if any of the following is true:

• server.target.domain.domainDir environment property is set and value does not matches domain
• server.target.domain.configDir environment property is set and value does not matches configuration
• server.target.standalone.serverDir environment property is set and value does not matches standalone
• server.target.standalone.configDir environment property is set and value does not matches configuration.
