Add hot reloading to oap1

[raymondjacobson]

Enable hot reloading on https://node1.oap.devnet by default. Takes 4-5s to come up on file save.

Not sure why we removed hot reloading altogether, that feels silly to have done?

Also made make default command run make up. If you want to restart everything, make up still works as is.

Tested:

• Ran make up
• Updated health check while tailing logs
