Get select license info from Qlik Sense server

[mountaindude]

Should be optional feature limited to non/low-sensitive info.

Example:

• Flag indicating whether server license has expired or not
• License expiry date
• Remainging days in server license

Status is checked at configurable intervals and sent to console log.
Other destinations can be added (handled in separate GitHub tickets).

Data is available at QRS endpoint /qrs/license/.
The returned JSON contains a keyDetails property which needs to be parsed to get license expiry dates for the various components included in the Qlik Sense license that is installed.

Output to console log will be either as info or warn, depending on whether number of remaining days in the server license is more or less than a threshold value set in the Butler config file.
