In case of IP reuse locally there was a race condition
that was leaving the overlay namespace with wrong configuration
causing connectivity issues.
This commit introduces the use of setMatrix to handle the transient
state and make sure that the proper configuration is maintained

Deletion of the dynamic mac is expected to work only if there was active
traffic with that endpoint and a dynamic entry exists. It can also age
out. Hence the mac removal failing is not error. Removing it to make the
debugging easier when parsing the logs.

When stale delete notifications are received, we still need to make sure
to purge sandbox neighbor cache because these stale deletes are most
typically out of order delete notifications and if an add for the
peermac was received before the delete of the old peermac,vtep pair then
we process that and replace the kernel state but the old neighbor state
in the sandbox cache remains. That needs to be purged when we finally
get the out of order delete notification.

- Maps 1 to 1 with container's networking stack
- It holds container's specific nw options which
before were incorrectly owned by Endpoint.
- Sandbox creation no longer coupled with Endpoint Join,
sandbox and endpoint have now separate lifecycle.
- LeaveAll naturally replaced by Sandbox.Delete
- some pkg and file renaming in order to have clear
mapping between structure name and entity ("sandbox")
- Revisited hosts and resolv.conf handling
- Removed from JoinInfo interface capability of setting hosts and resolv.conf paths
- Changed etchosts.Build() to first write the search domains and then the nameservers
