[BCN] Config Refresh

[MicahMaphet]

Reload config files bitcore-node bitcore-node workers reload their configs on SIGUSR1 Use the scripts/reloadConfig.sh to send SIGUSR1 to pids contained in new pids directory Reload all workers:

$ ./scripts/reloadConfig.sh
Reload configs for all workers: 264191 242416

List active workers:

$ ./scripts/reloadConfig.sh list
all
api

Reload configs for specified workers:

$ ./scripts/reloadConfig.sh all api
Sent reload signal(s) SIGUSR1 to 'all api'
pids: 264191 242416

Not all of the config options reload properly, e.g. numWorkers. What is known to work:

• changing peer connections
• disabling and enabling peers
• RPC connections (at least for the purposes of the /fee route)
• API port
