Starting view och json after manager is running cause metrics server to be started a second time

[jhoglin]

I'm too new with Python but this global handling must be broken somhow.

Swar-Chia-Plot-Manager/plotmanager/library/utilities/instrumentation.py

Line 4 in a4621ff

PROCESSED = False

Starting manager first

python3 manager.py start
Plot Manager has started...

then start the view, the view process has no knowledge about the global PROCESSED from start of manager, so it will try to start a second server using the same port and the result is:

python3 manager.py view
              ->   processed 1 False.    # MY OWN PRINT TO DEBUG THIS

I have the same issue

Tried to fix :) #660

Anyway, it's not working correctly. When I restart the manager it fails to update values, so for now it responds only with 1 job running..
