OpCreds Fabric Management functionality

[shana-apple]

• Adds functionality for reading the fabrics list attribute which gets updated after any updates to the admin pairing table.
• Adds functionary for removeFabric.
• Adds a setFabric command as a temporary command before AddOptCert is implemented. This allows the commissioner to set their vendorId for their fabric and returns to them their fabricId
• Remove the label field of FabricDescriptor struct because a bug in the generated code makes it that the whole list is corrupted if if is present (we need to fix whatever is wrong with OCTET_STRING in lists). This means that the UpdateFabricLabel implementation is not included in this patch.
• UI updates in the iOS demo app

This needs restyling so it doesn't change every single generated file.

Adding changes requested for the storage delegate coupling - it seems we are trying to simplify ember callbacks however this introduces extra globals inside the transport layer.

Approving, however please address other comments from mspang@ and resolve conflicts.

I would also note that PRs involving generated code are very hard to review properly.

Agreed, I tend to add the regenerated files in a separate commit but we should have a script that regenerates them on push on build or something.
