Issue # 1374:
    Use the latest Dataflow SDK version.

Issue # 1373: Unable to deal with new cloudbuild.googleapis.com/Build assets:

    The core issue was that the discovery_name of this new asset type is
incorrectly reported as cloudbuild.googleapis.com/Build rather than 'Build'. Try
to deal with that by correcting any discovery_name with a '/' in it. But there
are other fixes necessary to speed processing.

Other performance/bug fixes:

- Use the discovery document generated schema if we have one over any resource
  generated one. This is a big performance improvement as determining the schema
  from the resource is time consuming, it's also not productive as if we have an
  API resource schema, it should always match the resource json anyways.

- Add ancestors, update_time, location, json_data to discovery generated schema.
  This prevents those properties from being dropped if we always rely on it.

- Sanitize discovery document generated schemas. If we are to always rely on
  them, it's possible they could be invalid, so enforce the bigquery
  rules on them as well.

- Use copy.deepcopy less, only when we copy a source into a destination field.

- Prevent bigquery columns with BQ_FORBIDDEN_PREFIXES from being created. There
  are some bigtable resources that can include these prefixes.

- Some BigQuery model resources had NaN and Infinity values for numeric fields.
  Try to handle those in sanitization.

- When merging schemas, stop after we have BQ_MAX_COLUMNS fields. This helps to
  stop the merge process earlier. (It can take forever if there are many unique
  fields and many elements).

- When enforcing schema on a resource, recognize when we are handling addition
  properties and add the additional property fields to the value of the
  additional property key value list in push_down_additional_properties. This
  produced more regular schemas.

- Add ignore_unknown_values to the load job so that we don't fail if resource
  contains fields not present in the schema.

- Accept and pass --add-load-date-suffix via main.py.

- Better naming of some local variables for readability.

- Some format changes suggested by Intellij.
