Add support for random modifiers on fields

[rmurthy716]

Can we support choice: random for all the different modifiers?

Changes are required in artifacts/openapi.yml from my understanding. I can make the necessary changes if we are ok with adding this to the model.

Hi @rmurthy716 - to add a choice:random will require changes in the openapiart repo under x-field-pattern extension.
Random was initially proposed for the x-field-pattern but was subsequently dropped as it was decided to leave it up to the tester to supply values that were random.
If the extension is to be extended then random should be qualified - ie repeatable random, random etc.

Right. The other reason was that we needed all OTG implementations to generate the same stream of packets. So 'random' for Ixia-c would have to generate the same 'random' for say TRex. What are our use-cases for random?

The use case is for load balancing hashing algorithms with random TCP ports. This is coming from a scan of a test plan shared with us.
