Added from/to filters to minder history list.

This change adds `--from` and `--to` optional flags, which let the
customer specify a time window for evaluation times. Allowed formats
are those supported by the library we're currently using (viper) and
are listed
[here](https://github.com/spf13/cast/blob/48ddde5701366ade1d3aba346e09bb58430d37c6/cast_test.go#L934-L952).

Fixes #3927
