Subject: [PATCH] Fix rates for Octopus integration v8.0.0

With the release of v8.0.0 of the Octopus integration a breaking change
was made to the rates. We now need to read the `all_rates` attribute,
use the `valid_from` attribute on each rate instead of `from`, and the
`value_inc_vat` attribute instead of `rate`.
