Make sure to always explicitly set namespace for all
kernel bound network operations irrespective of whether
the operation is performed in init namespace or a user
defined namespace. This already happens for user defined
netns. But doesn't happen for initial netns that libnetwork
runs in.

- 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
