Remove oclif and replace with commander

The full problem and discussion about which tool can be found on our internal issue: https://github.com/netlify/pod-workflow/issues/343

@lukasholzer @erezrokah would it make sense to use commander instead of minimist too? minimist is currently used in netlify-lambda only:

src/lib/functions/runtimes/js/builders/netlify-lambda.js:5:const minimist = require('minimist')
src/lib/functions/runtimes/js/builders/netlify-lambda.js:22:    const match = minimist(script.split(' '))

Yes it will. We were trying to scope down this big refactoring as much as possible.
This especially makes sense since netlify-lambda uses commander too https://github.com/netlify/netlify-lambda/blob/1645b4aff5914eff4c4952dfa26ad57b78599188/bin/cmd.js#L7
