41fd4eab5c envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) 
A new package can also later record/report which knobs are checked and
set. It also makes the code cleaner & easier to grep for env knobs.

d5a7eabcd0 control/controlbase: enable asynchronous client handshaking. 
With this change, the client can obtain the initial handshake message
separately from the rest of the handshake, for embedding into another
protocol. This enables things like RTT reduction by stuffing the
handshake initiation message into an HTTP header.

Similarly, the server API optionally accepts a pre-read Noise initiation
message, in addition to reading the message directly off a net.Conn.

aae622314e tailcfg, health: add way for control plane to add problems to health check 
So if the control plane knows that something's broken about the node, it can
include problem(s) in MapResponse and "tailscale status" will show it.
(and GUIs in the future, as it's in ipnstate.Status/JSON)

This also bumps the MapRequest.Version, though it's not strictly
required. Doesn't hurt.

types/key: add a special key with custom serialization for control private keys (#2792) 
* Revert "Revert "types/key: add MachinePrivate and MachinePublic.""

This reverts commit 61c3b98a24.

Signed-off-by: David Anderson <danderson@tailscale.com>

* types/key: add ControlPrivate, with custom serialization.

ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.
