HARMONY-1781 - Update to harmony-service-lib-py==2.0.0.

[owenlittlejohns]

Description

This PR updates most of the dependencies for this service. Most notably, the harmony-service-lib-py dependency is bumped to v2.0.0. This is a breaking change for that package, as it repackages the functionality under a namespace of harmony_service_lib instead of harmony. (See here for more information).

A couple of other quick notes:

• I updated the other dependencies where I could, because that's a good practice. I couldn't bump numpy because of the requirements of earthdata-varinfo. (That could/should be improved in the future)
• I've put a couple of PRs up against this service to help the Harmony team test changes to harmony-service-lib-py. The main reason for choosing this service is that it doesn't have much development going on it it, and it's a pretty lean service to update.

Jira Issue ID

HARMONY-1781

Local Test Steps

• Pull this branch.
• Build the service image, test image and run the tests locally. ./bin/build-image && ./bin/build-test && ./bin/run-test
• Start a local Harmony instance that includes the regridding service (having harmony-regridder in the LOCALLY_DEPLOYED_SERVICES variable in .env)
• Run the Harmony Regridding Service regression test suite against your local Harmony instance - although note, I was having issues where my local instance could not download the EEDTEST collection files hosted in the Harmony UAT AWS account. I think those issues are unrelated to this change (and indeed the path of the function trying to do the download included harmony_service_lib, which is a good sign).
