populate_mirror_registry | Use a tmp folder for oc/kubectl/opm binaries

[ramperher]

• Right now, we are placing all the binaries in /usr/local/bin
• It may happen that, if we are sharing the jumphost between multiple OCP clusters, this file path is common for all the deployments.
• It is better to have a dedicated folder for each deployment to save the binaries and use them whenever they are needed.
• Doing this in the populate_mirror_registry.
• Apart from this, we keep the oc and kubectl binaries in /usr/local/bin directories, since they are used in other roles. It is not the case of opm binary.
