Initial NTP-Status integration include file.

This currently supports the standard ntpd package, which must be pre-installed, and as well as the enhanced Linux one (where ntpq has a wide option). Needs more testing across OSes

Requires bash, will not work with default Bourne or Korn shells as it requires bash specific extensions.

How to use:

Download at least the XML file or use the remote "raw" URL direct from github for systems that have external public access and once validated add an NTP-Status sampler to your chosen Managed Entities or into your preferred infrastructure monitoring Type.

Additionally the environment variable NTPHOST can be defined to query a remote host. Default is a localhost connection.

The PATH environment variable is defined in the default sampler as most users do not have ntpq in their default path.

TODO:

• Windows support for Meinberg NTPD
• Chrony support (Different sampler)
