Currently users have to write code in order to enable java 8 date/time types in Spin
The idea behind this feature request would be to provide spring boot auto configuration that did this - triggered by a maven dependency.
The exact configuration could then be done be done as (spring boot) yaml parameters.
For reference, this is what a user would do:
1 - add the maven dependency
2 - register javatimemodule through a DataFormatConfigurator
3 - create file entry in META-INF/services/org.camunda.spin.spi.DataFormatConfigurator in order to register component (CamundaJacksonFormatConfigurator )
