psql: Make default \watch interval configurable
The default interval for \watch to wait between executing queries,
when executed without a specified interval, was hardcoded to two
seconds. This adds the new variable WATCH_INTERVAL which is used
to set the default interval, making it configurable for the user.
This makes \watch the first command which has a user configurable
default setting.
