[WIP] feat: add masking to list resources

[ishanarya0]

We are introducing secret masking feature in entropy.
List of secrets can be defined as environment varibale for each module kind as follows:

FIREHOSE_SECRET : SINK_REDIS_AUTH_PASSWORD,big_query_sink_credential,dlq_gcs_sink_credential

The secret can be in resource config as well as resource output.
We should be able to configure nested secret as rootfield.nest1.nest2

On Get and List resource these fields should be nested.
On updated, if user passes value for these fields as masked value, entropy should use the previous value in the resource.
