SCTP Support (#1341)

* Add SCTP as InternetProtocol

* Add SCTP as ExposedPort

* Fix documentation in InternetProtocol

* Change import format to how it was previously

* Fixed test failing as JSON mapper uses alphabetical order.

* Tests now use "arrayContainingInAnyOrder" instead of "arrayContaining". Casting test/expected JSON to Map for unordered comparison rather than strict text comparison

* Changed to cast to generic JsonNode class, can then compare entries as arrays
