Drop default log-level from error to warn

Our users are missing certain warning messages that would
make debugging issues with Podman easier.

For example if you do a podman build with a Containerfile
that contains the SHELL directive, the Derective is silently
ignored.

If you run with the log-level warn you get a warning message explainging
what happened.

$ podman build --no-cache -f /tmp/Containerfile1 /tmp/
STEP 1: FROM ubi8
STEP 2: SHELL ["/bin/bash", "-c"]
STEP 3: COMMIT

$ podman --log-level=warn build --no-cache -f /tmp/Containerfile1 /tmp/
STEP 1: FROM ubi8
STEP 2: SHELL ["/bin/bash", "-c"]
STEP 3: COMMIT
WARN[0000] SHELL is not supported for OCI image format, [/bin/bash -c] will be ignored. Must use `docker` format

These messages will no longer be lost, when we default to WARNing level.
