PostgresNode::is_started provides information about a manually started node. It is "set" in start method and is reset in stop, kill methods. These methods do not verify this flag. So we cannot stop and start our node twice. An updated implementation of kill method raises InvalidOperationException when our node is not running.

PostgresNode::is_started provides information about a manually started node.
It is "set" in start method and is "reset" in stop, kill methods.
These methods do not verify this flag and do not use for other aims - for example to ignore the second start or stop of a node.
So we cannot stop and start our node twice.
An updated implementation of kill method raises InvalidOperationException when our node is not running.
This patch allows to use testgres in code where a node started or stopped explicitly, not via start/stop/kill methods.
