I adjusted the P4 implementation and export related parameters for IPFIX to support the new format introduced by the IOAM Template Option.

The Aggregation Trace Option for IOAM is now transported as a template within the IOAM template option.

The format to transport the aggregated network telemtry data is now as follows:

  0                   1                   2                   3
  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

I adjusted the P4 implementation and export related parameters for IPFIX to support the new format introduced by the [IOAM Template Option](https://www.ietf.org/archive/id/draft-mbci-ippm-ioam-template-option-01.html). The [Aggregation Trace Option for IOAM](https://www.ietf.org/archive/id/draft-cxx-ippm-ioamaggr-04.html) is now transported as a template within the IOAM template option. The format to transport the aggregated network telemtry data is now as follows: ``` 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Namespace-ID | Template-ID | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Flags | IOAM Data Param | Aggregator | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Aggregate | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Auxil-data Node-ID | Hop Count | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ ```

Restructure project to support the selection of the IOAM option to be used 556ea4c4a1

At the IETF hackathon it should be straight forward to show the different
IOAM Options in action. The three available options should be template,
aggregation and gob. The complete PoC including networking and monitoring
should be fully functional.
