Alan Parra 0ecf31de0e Restore terminal state on interrupt or exit (#13382) ...

Fixes an issue with ContextReader on `bash` where abandoned password reads cause
the terminal to remain "locked" even after `tsh` exits. This happens on
interrupts but also on regular exit if the user picks a security key in the dual
security key/OTP login prompt.

Doesn't seem to affect shells like `zsh` or `fish`.

Repro steps:

```shell
$ bash

# repro #1
$ ./tsh login --proxy=example.com
> Enter password for Teleport user llama: <CTRL-C>
# shell is now locked

# repro #2
# (Use an account with security key and OTP MFA.)
$ ./tsh login --proxy=example.com
> Enter password for Teleport user llama: <enters password>
> Tap any security key or enter a code from a OTP device <taps security key>
# shell is now locked
```

* Restore terminal state on interrupt or exit
* Notify prompt on tsh exit
* Review: context.WithTimeout and Notify on os.Exit
