take advantage of click's type validation/coercion

(saves us having to write the stuff ourselves). Also adds a small
click plugin to do datetime parsing.

Sample output:

```
[leohemsted:~/dev/api]$ flask command create_provider_rates --help
Usage: flask command create_provider_rates [OPTIONS]

  Backfill rates for a given provider

Options:
  -p, --provider_name [mmg|firetext|ses]
                                  [required]
  -c, --cost FLOAT                Cost (pence) per message including decimals
                                  [required]
  -d, --valid_from DATE           [required]
  --help                          Show this message and exit.
[leohemsted:~/dev/api]$ flask command create_provider_rates -p ses -c 1.234 -d invalid
