Add icp network run --background, and icp network stop

https://dfinity.atlassian.net/browse/SDK-2373

I tried this out but it doesn't seem to be working as expected:

❯ icp network run --background
PocketIC path: /Users/raymond/bin/pocket-ic
Port file: /Users/raymond/dev/dfinity/icp-cli/examples/icp-motoko-recipe/.icp/networks/local/pocket-ic/port
Starting PocketIC...
PocketIC started on port 60180
..... snip snip .....
Press Ctrl-C to exit.  <<<<<<<<<<<<<<<<< Maybe we don't print this in background mode


❯ ps aux | grep pocket

So it looks like the pid being recorded is not the correct one.

[viviveevee]

The pid that gets recorded is not the pocketic pid, but the equivalent of icp network run, so you need to search for it with ps aux | grep icp
