[DE-6014] Add support for limited access keys

[edwinpav]

Linear issue: https://linear.app/scale-epd/issue/DE-6014

Note: This allows the api_key and limited_access_key to be used together as well as individually (let me know if you think this shouldn't me an option)

Testing:
After updating tests to support limited access keys, all tests that passed before this change still pass via poetry run pytest -q -m "not integration"

Example usage with poetry:

• First do poetry install.
• The examples below use an API_KEY and a LIMITED_ACCESS_KEY associated with userID: 68921622befbf26f9e535024: https://dashboard.scale.com/nucleus?spoof=68921622befbf26f9e535024

poetry run python - <<'PY'
import nucleus
c = nucleus.NucleusClient(limited_access_key="<LIMITED_ACCESS_KEY>")
print([d.name for d in c.datasets])
PY

# Output
['Test4', 'test_3', 'test2', 'test1']

poetry run python - <<'PY'
import nucleus
c = nucleus.NucleusClient(api_key="<API_KEY>", limited_access_key="<LIMITED_ACCESS_KEY>")
print([d.name for d in c.datasets])
PY

# Output
['Test4', 'test_3', 'test2', 'test1']

poetry run python - <<'PY'
import nucleus
c = nucleus.NucleusClient(api_key="<API_KEY>")
print([d.name for d in c.datasets])
PY

# Output
['Test4', 'test_3', 'test2', 'test1']

poetry run python - <<'PY'
import nucleus
c = nucleus.NucleusClient()
print([d.name for d in c.datasets])
PY

# Output
nucleus.errors.NoAPIKey: You must provide credentials to NucleusClient: pass api_key or limited_access_key, or set NUCLEUS_API_KEY or NUCLEUS_LIMITED_ACCESS_KEY.

Every other test (only 1 other one) that uses customObjectIndexingJobId is also skipped due to an apparently known issue with customObjectIndexingJobId. See here. Thus, this fix should be for a separate pr.

python:3.7-buster was not even building in the circleci pipeline because it seems to be EOL and thus not supported anymore. Please advise if there is a better alternative than the one I chose.

This will support using both api_key and limited_access_key at the same time. Let me know if it's better to just gate to using one or the other

Can you include the output above when checking for something that does return if you have a full api key, but not if you only have a limited access key?

The only failing test here seems to be an unauthorized error?

That's a flaky test that occasionally passes/doesn't pass, but I terminated run 4 which was the hanging one so technically doesn't show up as failed:

Limited access key means you can only access the Nucleus service with it, so all Nucleus functionality should be available
