Support boolean values in resolveOptions func

Reference: https://github.com/confio/ts-relayer/pull/173/files/af3e18ccdaeb5e9f817c1d0372c0ffba6d12993c#r622158971

Allow for boolean values in resolveOption function: https://github.com/confio/ts-relayer/blob/main/src/binary/utils/options/resolve-option.ts

e.g.

const enableMetrics = resolveOption('enableMetrics', { required: true, boolean: true })(
  flags.enableMetrics,
  process.env.RELAYER_ENABLE_METRICS,
  app?.enableMetrics,
  false,
)

Currently, it's only capable of resolving strings to string/integer.

I wonder if this is not an overkill. If boolean flag is not passed, it gets a false value and we never need to throw. 🤷

I guess you are right. Maybe just the non-required version?

Yeah, I'll try to come up with something nice. Let's see...
