Refactor glbc-deployments repo

[pmccarthy]

What
With the global load balancer (GLBC) being replaced by the Multi Cluster Traffic Controller (MCTC) we should look to rename the glbc-deployments repository to something more generic such as kcp-deployments while updating Argo configurations to support this name change.

From there we should also look at updating or replacing directory names and configurations within the repository to use MCTC configurations instead

Done

• The glbc-deployments repository has been renamed to kcp-deployments
• Sub directories and config files within the glbc-deployments repo are updated to support MCTC
