fix: add schema rules for 'baseurl' and 'metalink' in yum repo config (#5501)
At least one of (or both) 'baseurl' or 'metalink' should be provided for yum
repository specification. Add schema changes to enforce it. Without this,
with just 'metalink' property set, one would get the schema validator error

Error: Cloud config schema errors: yum_repos.epel-release: 'baseurl' is a required property
