KAFKA-3622: Use descriptive error message if port number is missing from url
A new exception is thrown in *parseAndValidateAddresses* method when the
port number is missing from the url.
The change was not trivial as the previous implementation of *getHost* and
*getPort* both returned *null* if ex. the port number was missing from the url.
To fix this behaviour I added some extra test cases and examples to the
unit tests with the expected behaviour and modified the *HOST_PORT_PATTERN*
regex and the above mentioned methods.

> When I try to set up MirrorMaker with *bootstrap.servers* missing the port

> ... 12 more
> {code}
> This message doesn't suggest that the port number is needed in the
> *bootstrap.servers* configuration which causes confusion for users who try to
> set this up for the first time.
> The above *ConfigException* message should be shown:
> {code}
> Missing port in bootstrap.servers: 127.0.0.1
