Some debuggers have much more flexible ways of setting breakpoints than VSCode currently supports (e.g. set breakpoints by regex). Would be nice if breakpoints created via commands in debugger console were reflected in the UI.

I'd suggest adding a new notification message to the protocol, which adapter can send when a breakpoint is created/deleted. It should include a "cookie" that needs to be passed back to the adapter in order to re-create the breakpoint.
