Most of the time, rates are computed in a loop by using `<res.currency>._convert`. This leads to a lot of round trips with the database. This PR is caching the value for a whole transaction. In order to do that, the non stored field `rate` has new (missing) contextual dependencies: the arguments of `_get_conversion_rate`. This allows to move the actual computation of the rate to the computed field, and `_get_conversion_rate` is now only a proxy to avoid playing with the context manually; also kept for backward compatibility. Other solutions were considered: * `ormcache`, but we want to avoid creating multiple caches and reduce the possibility to have inter dependent caches. * managing a local cache everywhere, which is cumbersome and error prone * a helper for the previous option by using a converter factory, but it is still an issue when the convert function is called from multiple call functions because the cache isn't shared then.
