Import format for Collections

[michaelbromley]

Is your feature request related to a problem? Please describe.
There currently exists an (undocumented) CSV-based import format for Products & ProductVariants. Also a very basic JSON-based format exists for creating Collections. However, this format is very limited. Missing features are:

• Set assets for Collection
• Set visibility
• Set description
• Set multiple filters
• Set hierarchy (specify parent)

Describe the solution you'd like
A new format, similar to the product CSV format might make sense. The trickiest part will be to come up with a way to specify filters in such a format. However, this should be very much doable since the CollectionFilters are already string-serializable.

A csv data import is very much needed in real world deployment. I have 1900 sku as google sheets data. The data is formatted as woocommerce product import csv schema here. It might help in creating a robust product import functionality.

There actually is a CSV import format - it's already used by the e2e tests but it's just not documented yet. I'll have to get around to that soon. You can learn a bit about it from these testing docs. FYI I am using it myself to import ~10k SKUs into a Vendure project.
