anvil reverted back to centos6, now different from blues
Created by: sarich
anvil nodes are using centos6 and soft keys again, while the rest of blues are using centos7 and modules. This commit reverts anvil to using the old system.
During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.
