[rgc183]

Fixes # (issue)

For prometheus exporter, required dependencies are not loaded in repository.bzl. When Opentelemetry is imported in some other project, these dependencies are missing.

@rgc183 Thanks for the fix. You would need to sign the CLA before you can contribute. Also, need to fix the code format as described here - https:/open-telemetry/opentelemetry-cpp/blob/main/CONTRIBUTING.md#how-to-send-pull-requests

@rgc183 Thanks for the fix.

Please fix the clang-format (extra line), see from the build logs:

diff --git a/bazel/extra_deps.bzl b/bazel/extra_deps.bzl

@rgc183 - let us know if you need help with formatting, or have issues with CLA signing?

[rgc183]

@lalitb Please give me sometime, I am working with my organization to get CLA approval and some sign-offs.

LGTM after CLA signed,

[rgc183]

@lalitb As a corporate contributor, when I select my organization, there is list of people I see as CLA managers. I do not see how to add new person to send an email to. Also, the person mentioned in the list, I cannot locate him internally.
I have internal approval to contribute to this project.

Created another MR: #1795 from my corporate account. Closing this one.
