Right now Queue Manager metrics are registered when the metrics struct
is created, which happens before a changed queue is shutdown and the old
metrics are unregistered. In the case of named queues or updates to
external labels the apply config will panic due to duplicate metrics.
Instead, register the metrics as part of starting the queue as we always
guarantee that Stop will be called before a new Start.

Added optional configuration item role, defaults to 'container' (backwards-compatible).
Setting role to 'cn' will discover compute nodes instead.
Human-friendly compute node hostname discovery depends on cmon 1.7.0:
c1a2aeca36
Adjust testcases to use discovery config per case as two different types are now supported.
Updated documentation:
* new role setting
* clarify what the name 'container' covers as triton uses different names in different locations
