[Exporter] add fix for prometheus exporter build

[rochaudhari]

Signed-off-by: Roshan Chaudhari rochaudhari@nvidia.com

Fixes #1728

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

As of now, CI build is failing for #1791, this PR can be merged once the build is fixed.

@rochaudhari - CI test is failing for code formatting. Can you fix the formatting as suggested here - https://github.com/open-telemetry/opentelemetry-cpp/blob/main/CONTRIBUTING.md#how-to-send-pull-requests

Strange! After running format.sh as well, the file looks same. I updated the patch again.
