(content-addressable-pipeline-snapshots-1) Elimate default_value from graphql schema

Since this is unused, no need to include it in the snaps. This
will make content-addressability easier as the default value as string
is a pretty unstable thing to include (depends on python rev and deps)

Depends on D2331
