Temperatures should be logged from Juniper devices

[lunkwill42]

Is your feature request related to a problem? Please describe.

Juniper has always had poor support for ENTITY-MIB, and has no support for ENTITY-SENSOR-MIB. The values of internal temperature sensors in Juniper devices are presumably available in some proprietary MIB.

Describe the solution you'd like

NAV needs to support the collection of temperature data from Juniper devices. It should be an easy enough task once the proper MIB objects have been identified.
