[nasa/nos3#407] Unit test coverage

[jlucas9]

Provide a means to get unit test code coverage values for the sample component (and others once they have functional unit tests as well).

Requires the following merges to be completed and submodules updated prior to closure:

• [nasa/nos3#407] Commented out all but one SC unit test for now nasa-itc/SC#4
• [nasa/nos3#407] Added gcov to target link libraries for sim; nasa-itc/hwlib#9
• [nasa/nos3#407] Removed code coverage artifacts; nasa-itc/CFS_IO_LIB#3
• [nasa/nos3#407] Added coverage dependencies nasa-itc/deployment#16

Make sure we squash this one during the merge as well.

Closes #407

Is the sc app conflict blocking this?

Coverage reports look good!

Looking to update to newer version of artifact upload in CI to remove warning

With roberts artifact update, I see code coverage pass. I see code coverage artifacts available to download too via zip file.

Checked through the outputs. Awesome exhaustive report! Should be quite useful, and good for moving onto the next step (improving coverage across apps). Just looks like we need to do a merge dev or update a couple sub mods before merging this.

Reviewed the pull request. Changed files look reasonable. Reviewed the code coverage reports and they looked reasonable as well. This pull request is approved.

Coverage.zip file was available for download and broke down test results when analyzed
