Expose a terminal API option to pause when the shell is exited #15583
Description
This is a requirement for the tasks framework to be moved to using the integrated terminal. The idea is to allow extensions to optionally specify they don't want the terminal to go away immediately after the shell process is exited but instead wait for input.
This would allow the tasks framework (and other extensions) to run a command that exits the shell immediately afterwards, and then wait for a keystroke or for the terminal to be killed manually, for example:
gulp build
...
...
Press and key to close the terminal...
Proposed API:
export function createTerminal(name?: string, shellPath?: string, shellArgs?: string[], waitOnExit?: boolean): Terminal;
