The IF DOM collector start coroutine for Cisco NXOS SSH devices. The
purpose of this coroutine is to start the collector task. Nothing fancy.
Parameters
----------
device:
The device driver instance for the Arista device
executor:
The executor that is used to start one or more collector tasks. In this
instance, there is only one collector task started per device.
spec:
The collector model instance that contains information about the
collector; for example the collector configuration values.

This function is used to parse the IOS CLI text from the command
"show interfaces transceiver" into a dictionary whose
key=<if_name>
value=<dict>:
<tag>: <value>
<tag>_flag: <flag_value>
Where <tag> is the name of the DOM item such as "rxpower" and the <tag>_flag
is the Cisco marker (++,--,+,-) that indicates the DOM item exceeds a
threshold value.
Parameters
----------
parse_text : str
The CLI output obtained from the device
Returns
-------
The dictionary of output as described, if the output contains any transceivers.
None otherwise.
