DPL-206 - Support creating testing data from UAT actions into RabbitMQ (S=L; C=M)

[emrojo]

User story
As PSD developer I want to be able to create testing data using UAT actions that will write into RabbitMQ instead of a file if I select a checkbox in the UAT actions method.

To be considered successful the solution must allow:

• Add a new UI checkbox to indicate if is to write to rabbitmq or to write to file
• Message written is following the JSON schema defined
• I can test the consumers stories using this UAT actions setting
