Add OCI detection via IMDS metadata server

OCIProvider previously only detected Oracle Cloud via the DMI vendor file
(/sys/class/dmi/id/chassis_asset_tag) and raised NotImplementedError for the
metadata server. This adds metadata-server detection so OCI is identified the
same way as the AWS/GCP/Alibaba providers.

What it does

• identify() now runs check_vendor_file() or await check_metadata_server().
• Queries the OCI instance metadata service (IMDS)
  _get_metadata / _get_metadata_v2 structure:
  • _get_metadata() — GETs the v1 endpoint (http://169.254.169.254/opc/v1/instance/).
  • _get_metadata_v2() — delegates to _get_metadata against the v2 endpoint
    (.../opc/v2/instance/) with the required Authorization: Bearer Oracle header.
  • Both run concurrently via asyncio.gather; check_metadata_server() returns any(...).
• Confirms it's really OCI (not just any host on the shared 169.254.169.254
  link-local IP) by checking the returned instance id starts with ocid1.instance..

Tests

• Added test_valid_metadata_server_check and test_invalid_metadata_server_check
  using aresponses, mirroring the AWS metadata tests.
• Full suite: 36 passed. flake8 --max-line-length 100 clean.

Hi @dgzlopes 👋

Just a heads-up on the red CI here — the failures don't seem related to this change:

• Python 3.9 / 3.10 / 3.11: pytest itself is green (36 passed), but the subsequent pre-commit install step crashes with ModuleNotFoundError: No module named 'pkg_resources'. The pinned pre-commit==1.11.2 imports pkg_resources, which was removed in newer setuptools (the runners now get setuptools 83). So any PR would hit this.
• Python 3.7: actions/setup-python@v2 can no longer provision 3.7 on current GitHub runners (Version 3.7 with arch x64 not found).
• Python 3.6: the job hangs until the 24h timeout for the same reason.
• Python 3.8 passes end-to-end, and DCO is green.

Is there anything blocking this from being merged? Glad to address any feedback.

@shimonelfassy-lang I will set the minimum Python version as 3.9 since older versions are way past EOL. I will raise a PR in a day or two and rebase yours.

@shimonelfassy-lang I can't rebase since the branch doesn't exist in this repo. Please rebase your PR (there will be small conflicts)

Hi, Thanks for the reply. I rebased and pushed. Can you take a look?
