Add config to enable/disable the safe.directory changes

[pit1sIBM]

Description

As a developer, I want to have the ability to enable/disable the safe.directory changes to .gitconfig.

Discussion

Right now in Openshift when using restricted-v2, the user ID is randomly generated from a range of UIDs e.g.

bash-5.1$ id
uid=1000710000(1000710000) gid=0(root) groups=0(root),1000710000

Naturally this ID doesn't have access to modify the global config by default. But even if I set the config during build at the system level, this still fails which isn't ideal. I can modify permissions but it would be nice to have oper8 just pick up my system config, instead of trying to create its own config file.

Acceptance Criteria

• Unit tests cover new/changed code
• Examples build against new/changed code
• READMEs are updated
• Type of semantic version change is identified
