[feature] Grafana stats logging

[m-rsmn]

I've been adding Grafana logging to my own quorum instance here and there but thought I'd make it into in actual PR if there's interest from others for it.

I thought about making it into a a separate program, that can be toggled with a flag / constant. That way it wont be enabled by default, but people wanting to run it, could easily turn it on by switching the flag.

I've got these stats covered already but I'm open to suggestions to include some more. I thought about including market statistics as well, but those have close to no purpose as quorum tracks market prices itself and has no way of getting that data back out of grafana.

General:

• current GCL
• GCL progress
• credits
• Creep count
• CPU used
• bucket level

Per room:

• RCL
• RCL progress
• current energy level

Programs:

• how many ran
• how much cpu the program took

Per Room:

• Room PRL
• Room Economy Level
• Current active lab reaction.

Programs:

• Each program's priority,
• Ticks between runs

Any progress on this?

No one made the PR, so nope. You might be able to look at his fork and make the PR yourself.

He doesn't have a fork of screeps-quorum.
