Create a utility to create a Schema based on some configuration

[p013570]

It is common for Gaffer Schemas to have quite a bit of boiler plate code, such as:

• commonly used types
  • count
  • time/date
  • visibility
• cardinality Entities on all vertices

It would be nice to be able to provide something like a CSV with headers and auto generate a schema based on the header names. Users would also have to tell Gaffer which columns in the CSV represented source/dest/vertex/group.

Linked to #1867

This should be done after #1657 and before #1536.
