fix leap_status value in chrony input plugin

[m4ce]

see #1982

[sparrc]

please fix the unit tests

[m4ce]

@sparrc, I must be missing something here but I don't see how my change would affect the output expected by the unit test? I see leap_status is expected to be set to "normal" and that's what it is set to. If you could point me out to the reason, I will be happy to fix it.

[sparrc]

@m4ce are you able to run the unit tests locally? your changes appear to be changing some exissting metrics, I don't have time to dig too deeply but I think if you can run the unit tests you can figure out what's changed

[m4ce]

@sparrc, no worries, I had a better look and the problem is the reference_id field. I've now commited a fix for it, let's wait for the unit test to finish.

[sparrc]

@m4ce can you add a unit test to verify that Leap Status: Not synchronised is getting represented properly now?

[m4ce]

@sparrc i've done that, i hope it looks good now.
