This moves all settings of timeout to one place. Also changes the
default timeout to 10 seconds, can probably solve the occasional
timeout when dataset commit active.
This commit tries to reduce expects fails in GitHub actions:
- wait_for only sends command when it's not empty
- increases the default expect timeout from 1s to 3s.
This makes expect run all cli-*.exp and posix-*.exp tests in RCP mode.
New scripts should use the function spawn_node in _common.exp to spawn
new processes. This is compatible with both simulation mode and RCP
mode.
