Subject: [PATCH] Update for missing snow files (#76)

This PR adds missing file actions to the snow observation yamls and also
makes an additional change to the obs staging yaml copy statement. These
modifications are one step to ensuring the snow DA does not cause an
operational failure if snow observation files are missing.
