feat:introduced graphql createFolderWithId, get all folders and deleteFolder

[kornelj]

To support migration tool developments (from confluence, etc), I had to extend grapqhl schema and resolvers locally to allow getting all asstes folders in one query (instead of executing 1000s to build up folder structure) and also added a new create that returns newly created asset folder ID to avoid having additional query to look up after create. Delete folder is needed to clean up mistakenly created folders since it's this feature is not available on UI. Even tough grapqh is made for UI mainly, I belive these new queries can be helpful for ther teams.
