libpod/config: use built-in TOML instead of manually merging
Instead of manually merging the configs, use the built-in features of TOMP to merge/extend the fields of a data type when encoding a file. This erases the need for the merge code in libpod/config and also addresses issues when merging booleans. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
