T2703: Use intrinsic identifiers/hashes for RawExtrinsicMetadata objects

Commits

rDMOD9da17a51dfaf: Rename the RawExtrinsicMetadata id field to target

Summary

This backwards-compatible change prepares the transition to give
RawExtrinsicMetadata an id field that is computed intrinsically from its
contents (using the HashableObject mixin).

The next steps will be:

release swh.model with this change
use the target attribute in swh.storage and swh.loader.core
release both modules
drop the id attribute and test again
release swh.model again
add a computed id field on all ExtrinsicMetadata objects

Related to T2703

Test Plan

tox + pytest in swh.storage and swh.loader.core

    Rename the RawExtrinsicMetadata id field to target
    
    This backwards-compatible change prepares the transition to give
    RawExtrinsicMetadata an `id` field that is computed intrinsically from its
    contents (using the HashableObject mixin).

Wouldn't it help the transition to also set an id attribute on instance? (You tell me, I don't know if it's actually used)

There's an id property for that purpose on the RawExtrinsicMetadata class (unless I'm missing something?)

oh yes, my bad. could you add a test for it?

(Use https://docs.pytest.org/en/stable/warnings.html so it doesn't show in pytest's output)

Right. Done.

(Use https://docs.pytest.org/en/stable/warnings.html so it doesn't show in pytest's output)

I've applied that to one of the tests, and migrated all the others to the proper attribute, so the tox output is deprecation warnings-clean.
