Script for initializing a new ingest.

[putmantime]

Background: Ingests are now just cloned from other ingests. This is error prone and doesn't handle adding ingest to the ingest.yaml.

Acceptance Criteria:

• Creates a templated ingest stub
• Adds ingest to ingest.yaml
• Needs to handle both ------new source directory(includes source directory, configs, documentation) ------adding a ingest to an existing source directory
