Add PostgresNode::command_fails_like()

This is useful to test for a command failure with some default
connection parameters associated to a node, in combination with checks
on error patterns expected.  This routine will be used by an upcoming
future patch, but could be also plugged into some of the existing
tests.

Extracted from a larger patch by the same author.
