Nuno Diegues 1ee540a166 TUN-5368: Log connection issues with LogLevel that depends on tunnel state 
Connections from cloudflared to Cloudflare edge are long lived and may
break over time. That is expected for many reasons (ranging from network
conditions to operations within Cloudflare edge). Hence, logging that as
Error feels too strong and leads to users being concerned that something
is failing when it is actually expected.

With this change, we wrap logging about connection issues to be aware
of the tunnel state:
 - if the tunnel has no connections active, we log as error
 - otherwise we log as warning

Igor Postelnik 8ca0d86c85 TUN-3863: Consolidate header handling logic in the connection package; move headers definitions from h2mux to packages that manage them; cleanup header conversions 
All header transformation code from h2mux has been consolidated in the connection package since it's used by both h2mux and http2 logic.
Exported headers used by proxying between edge and cloudflared so then can be shared by tunnel service on the edge.
Moved access-related headers to corresponding packages that have the code that sets/uses these headers.
Removed tunnel hostname tracking from h2mux since it wasn't used by anything. We will continue to set the tunnel hostname header from the edge for backward compatibilty, but it's no longer used by cloudflared.
Move bastion-related logic into carrier package, untangled dependencies between carrier, origin, and websocket packages.

Igor Postelnik 0b16a473da TUN-3869: Improve reliability of graceful shutdown. 
- Don't rely on edge to close connection on graceful shutdown in h2mux, start muxer shutdown from cloudflared.
- Don't retry failed connections after graceful shutdown has started.
- After graceful shutdown channel is closed we stop waiting for retry timer and don't try to restart tunnel loop.
- Use readonly channel for graceful shutdown in functions that only consume the signal
