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 https://github.com/containers/common/pull/624
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1855983
