yum errors with same repo twice about hpc-container-maker

Unfortunately I haven't found an elegant solution to this.

Here's the best I've come up with:

1. Ignore the return status of yum-config-manager --add-repo. This would involve adding a (non-default?) option to the yum building block that would use (yum-config-manager --add-repo https://developer.download.nvidia.com/devtools/repos/rhel7/x86_64 || true) instead of yum-config-manager --add-repo https://developer.download.nvidia.com/devtools/repos/rhel7/x86_64.
2. Remove the repo file at the end of the building block. This would involve adding a (non-default?) option to the yum building block that would run rm -f /etc/yum.repos.d/developer.download.nvidia.com_devtools_repos_rhel7_x86_64.repo after installing the packages.
3. Combine the nsight_systems and nsight_compute building blocks into a single nsight building block. The repo would only need to be added once, with options to individually enable / disable installing Nsight System and Nsight Compute. However, this would break existing recipes.

Thoughts?

@samcmill same. I was hoping there would be an option to ignore a repo if it exists on yum-config-manager, but unfortunately, there's not. 3 sounds like the best option if it didn't break existing recipes, so it's probably a non-starter. There may also be another tool down the line that uses the same repo, and it would break again. I like the first option as a quick hack since that command shouldn't fail anyways.
