This allows reusing the NoiseClient in other repos without having to reimplement the earlyPayload logic.

Not currently used, but will allow us to usually remove a round-trip for
a future feature.

In prep for a future change that would've been very copy/paste-y.
And because the set-dns call doesn't currently use a context,
so timeouts/cancelations are plumbed.

* tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field
This field allows the control server to provide explicit information
about how to connect to it; useful if the client's link status can
change after the initial connection, or if the DNS settings pushed by
the control server break future connections.

This turns 'dialParams' into something more like net.Dialer, where
configuration fields are public on the struct.

The connections returned from SystemDial are automatically closed when
there is a major link change.
Also plumb through the dialer to the noise client so that connections
are auto-reset when moving from cellular to WiFi etc.

This is so that we can plumb our client capability version through
the protocol as the Noise version. The capability version increments
more frequently than strictly required (the Noise version only needs
to change when cryptographically-significant changes are made to
the protocol, whereas the capability version also indicates changes
in non-cryptographically-significant parts of the protocol), but this
gives us a safe pre-auth way to determine if the client supports
future protocol features, while still relying on Noise's strong
assurance that the client and server have agreed on the same version.
Currently, the server executes the same protocol regardless of the
version number, and just presents the version to the caller so they
can do capability-based things in the upper RPC protocol. In future,
we may add a ratchet to disallow obsolete protocols, or vary the
Noise handshake behavior based on requested version.

Fix regression from 21069124db caught by tests in another repo.
The HTTP/2 Transport that was being returned had a ConnPool that never
dialed.

We want to close the connection after a minute of inactivity,
not heartbeat once a minute to keep it alive forever.
