Add command line options to Butler SOS

[mountaindude]

Similar to how Butler does it these days:

➜  src git:(master) node butler.js --help
Usage: butler [options]

Butler gives superpowers to client-managed Qlik Sense Enterprise on Windows!
Advanced reload failure alerts, task scheduler, key-value store, file system access and much more.

Options:
  -V, --version                output the version number
  -c, --configfile <file>      path to config file
  -l, --loglevel <level>       log level (choices: "error", "warn", "info", "verbose", "debug", "silly")
  --new-relic-api-key <key>    insert API key to use with New Relic
  --new-relic-account-id <id>  New Relic account ID
  -h, --help                   display help for command
➜  src git:(master)

The same set of CLI options are relevant also for Butler SOS.
