Ongoing Work On More Semantic-Typed API

This release, like the 20.01, continues the journey on defining the semantic-based types instead of storage-based types within the API, so you may have noticed this in the API changes.

Some of the changes are related to the infrastructure, and may be bugfixes, they do not change the CRC of the message but affect the representation on the wire. One particular commit we want you to pay attention to, is b5c0d35f, which fixes the bug with the enum representation on the wire - before it, even the enums declared as u8 or u16 were represented as u32 in the API messages.

Another important commit we would like to call out explicitly as well is 7dd63e5c, which pinned the address_family and ip_proto enum types to be u8 instead of the default u32.

The above two commits will be primarily interesting for those who work with the low-level APIs on VPP - the API frameworks should make these under-the-hood changes transparent. However, we decided to call these out, given that for those affected these will be pretty important changes.

Another commit, that does not have the immediate impact at the moment, but that is poised to improve the user interaction with the API is 5c318c70. This adds the tooling and ability to implement a structured process, by which the API messages can evolve, while minimizing the impact to the API users.
