[Collection Creation] - Adds collection creation

[ggirotto]

Central issue to track the Collection creation for memo.

Why

User must be able to create and edit its own collections in the app, otherwise it would be constrained by the collections that are created by the community.

This functionality gives the opportunity for users to create and maintain specific collections, given how they see fit.

How

The collections creation should be considered completed after all issues below are closed.
