MaxCtrl: Raw REST API Calls

MaxCtrl is now able to perform raw HTTP GET calls that return the JSON data from the REST API. It also supports value extraction with JavaScript style syntax.

For example, extracting just the state of all servers as a JSON array can be done with the following command:

[markusjm@localhost ~]$ maxctrl api get servers data[].attributes.state
["Master, Running","Slave, Running","Slave, Running","Slave, Running"]
