Custom key

[pchampio]

DOC: dio-http-cache uses url as key.
Letting the user define custom keys for caching would enable users to share cache between requests.

Such a feature is interesting in the following example:
http://example.com/a/b
http://example.com/a/b?timestamp=1566563506431
http://example.com/a/b?timestamp=1566563506433
The API needs a timestamp GET parameter that cannot be shared between requests, be we would like to save them as ONE request in sqflite. (for MaxStale fallback)

The above case can also be solved by providing queryParameters at the buildCacheOptions level, where they could be ignore by the hash method.
