Exec is used to execute a command inside a running task. The command is to run inside the task environment.

The parameters are: * ctx: context to set deadlines or timeout * allocation: the allocation to execute command inside * task: the task's name to execute command in * tty: indicates whether to start a pseudo-tty for the command * stdin, stdout, stderr: the std io to pass to command.

If tty is true, then streams need to point to a tty that's alive for the whole process

* terminalSizeCh: A channel to send new tty terminal sizes

The call blocks until command terminates (or an error occurs), and returns the exit code.
