Support for consistent MAC address.

Right now, MAC addresses are randomly generated by the kernel when
creating the veth interfaces.

This causes different issues related to ARP, such as #4581, #5737 and #8269.

This change adds support for consistent MAC addresses, guaranteeing that
an IP address will always end up with the same MAC address, no matter
what.

Since IP addresses are already guaranteed to be unique by the
IPAllocator, MAC addresses will inherit this property as well for free.

Consistent mac addresses is also a requirement for stable networking (#8297)
since re-using the same IP address on a different MAC address triggers the ARP
issue.

Finally, this change makes the MAC address accessible through docker
inspect, which fixes #4033.

Merge pull request #8371 from aluzzardi/f-consistent-mac

Support for consistent MAC address.
Multiple fixes to the cli.md document.

*. Fixed headings so the side menu will now be consistent. Some sections
had H3s that were displaying and others did not leaving the left menu
very mismatched.

* Fixed several spelling errors.

* Re-formatted several long lines and badly laid out paragraphs.

* Fixed several double backticks.

* Added backticks to several outputs and variables.

* Removed two issues that are no longer valid.

* Removed several double spaces and extra lines.

Network Allocation: Proper rollback in case of failure allocation.

Container: Make allocateNetwork and releaseNetwork public.

Since we are moving network allocation outside of container scope (it
will be managed by create/destroy), those functions need to be
accessible from the outside.

Container: Add restore network functionality.

RestoreNetwork() allows the container to restore its NetworkSettings (IP
and public ports).

Stable Networking: Keep the same network settings across container restarts.

This change will allocate network settings (IP and public ports) at
container creation rather than start and keep them throughout the
lifetime of the container (i.e. until it gets destroyed) instead of
discarding them when the container is stopped.
