session: add support for proxying apps
To enable this, applications set the proxy flag in their attach requests
and pass the transport protocols they want to act as proxies for as part
of the attach options.
When proxy is enabled, session rules that point incoming packets to the
proxy app are addedd to the local and global session tables, if these
scopes are accessible to the app. In particular, in case of the former,
the rule accepts packets from all sources and all ports destined to the
namespace's supporting interface address on any port. While in case of
the latter, a generic any destination and any port rule is addedd.
