Add support for new experiments API changes

[jyu00]

What is the expected enhancement?

Support the new experiments API changes:

• [ ] make device_components optional for analysis results
• [ ] make fit optional for analysis results
• support updating experiment extra and tags
• support device backend name
• support excluder_owner and owner_only when filtering experiments
• typo in public_only docstring
• new verified boolean
• new free-form notes in experiments

It's now also possible to filter experiments in GET /experiments by owner using the special me and !me values:

• GET /experiments?owner=me: only return experiments owned by the user making the request
• GET /experiments?owner=!me: only return experiments available to but not owned by the user making the request

@mriedem FYI since these new changes are to support Ignis, I'm going to wait until the Ignis interface (Qiskit/qiskit#5499) is finalized before working on this, since there will be a bit of interface change.

[mriedem]

OK, no problem. Would you want to split out the owner=me and owner=!me support stuff into a separate issue to be worked on outside of the Ignis changes, or is just everything held up on that interface change?

[jyu00]

Sure. owner=me can be done separately.
