Better tag selection
====================
The block was originally hooked onto the `external` tag under the
assumption that this was the tag used to allow external requests.
It's not, it's the tag for the "external" test suite, which is only
one of the test suites allowed to perform external calls. Hook again
onto `standard`, this might have some false positives (allow requests
which we'd rather block), but it should have a lot less false
negatives (block requests we want to allow).
Make Overrides Easier
=====================
Currently `_request_handler` raises a regular `ConnectionError`, this
is an issue because it passes some requests through, which could
themselves trigger genuine `ConnectionError`.
When overriding `_request_handler` to implement fallbacks for bespoke
URL mocks, these two cases need to be distinguishable as overrides
likely want to handle blocked requests, not actual failures.
Therefore `_request_handler` should a dedicated exception. This
exception should be a subclass of `ConnectionError`, so that blocked
requests are treated as regular connection failures by normal Odoo
code.
Class-scope
===========
Originally `_request_handler` was scoped on the instance with the idea
that it'd be a `mock` object, which individual tests could
`configure_mock`. This turned out not to work correctly, because
`Mock.side_effect` does not receive a `self`, hence the `Session` was
inaccessible and it was not possible to passthrough local requests.
While I moved to a regular `lambda` (because a direct method didn't
work either), I forgot to remove the `request_mock` attribute, and
didn't think that the block could now be lifted up to the class
scope. Doing this, requests performed during a "standard" test case's
`setUpClass` are now also blocked, which they very much should be.
