Scrub podman commands to use report package

Refactor podman commands that have drifted from using c/common report pkg. Report pkg is needed to implement go template functions. Removed obsolete code from podman which exists in c/common. Latest template library added default newlines and method to remove them. Incorporated needed changes in c/common PR below. Depends on containers/common#624 Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1855983 Signed-off-by: Jhon Honce <[email protected]>
