TRA-3317 Tap and show outbound traffic (#83)

* Tap outgoing: If --anydirection flag is passed with HOST_MODE, tap by source IP.

* Moved ConnectionInfo from http_matcher to http_reader.

* Generalized shouldTap in stream factory to get more properties.

* tap reports IsOutgoing property of tcp connection.

* gofmt.

* CLI instructs tapper to tap outgoing connections.

* API saves IsOutgoing to DB and passes it to UI.

* Add a visual marker in the HAR list for outgoing messages.

* Fixed: Swapped src and dst.

* Resolver keeps a list of all ClusterIP services.

* Do not save HARs with destination ClusterIP services.

* CLI accepts flag that controls traffic direction.

* Indicate incoming/outgoing with icon instead of with border color.

* Fixed: Didn't filter messages to services in aggregator.

* Clearer syntax around the direction icon. Added title text.

* Fixed width around direction icon.

* Less repetition.

* Removed TODO.

* Renamed incoming -> ingoing.

* More verbose title text to image.

* Switched routine order for readability.
