meta-phosphor: Replace phosphor-rest with bmcweb

This patchset replaces the python based phorphor-rest implementation
with bmcweb, a c++ implementation.

bmcweb has several advantages to phosphor rest, and should be the
default implementation for new BMCs.  Some of the advantages include:
1. Authentication and authorization is based on PAM
2. Its written in a compiled language, which gives it more applicability
for low resource systems with lower memory.
3. It replicates all the existing phosphor-rest interfaces.
4. Smaller binary size.  The bmcweb binary compresses to 800KB at last
measure.
5. bmcweb implements a compliant redfish interface, which phosphor-rest
does not.
6. bmcweb has a selectable build, so features can be enabled/disabled
per platform as needed.
