net2cog - Ensure test suite does not fail for unconfigured environments.

[owenlittlejohns]

Description

This PR came up from skimming recent regression test failures for a Harmony production deployment. The cell that currently verifies the output for the first test will always try to run, even if there is no configuration information for an environment. In this case, production has no collection information, so none of the tests or verification should run.

This PR just wraps the cell in question with a check that things are configured.

Local Test Steps

• Checkout the main branch. Run the net2cog test suite (use instructions below). This will fail with NameError: name 'harmony_client' is not defined.
• Checkout this branch. Run the net2cog test suite (using same instructions below). This should now pass. Check the test/output/net2cog/Results.ipynb output - it should have print statements outputting that the cells were skipped.
• (Bonus), run export HARMONY_HOST_URL=https://harmony.uat.earthdata.nasa.gov, then re-run the test suite with ./run_notebooks.sh net2cog. The test suite should also still pass against UAT (but should take longer than the production run, because it's actually running the tests). Check the test/output/net2cog/Results.ipynb output - it should look like the tests were fully executed.

export HARMONY_HOST_URL=https://harmony.earthdata.nasa.gov
export EDL_USER=<your EDL user>
export EDL_PASSWORD=<your EDL password>

cd test
make net2cog-image
./run_notebooks.sh net2cog
