add config support for TCP Bridges

[andreas-ibm]

This is only barely tested, and not all the configuration settings will be applied by TCPBridges (e.g. the prefixes haven't been implemented and in direction hasn't been implemented.

Hi Andreas. Thanks - you need to fix the IP checks before I could merge this:

"The pull request did not pass Eclipse validation.

The following users do not have valid ECAs: [email protected]

The following users have invalid Signed-off-by footers: [email protected]"

It's the Eclipse way - for which there are good reasons.

yeah, saw the failures, took me a while to figure out how to "solve" them.. Think it's all done now?

[icraggs]

Yep. All good now.
