In the CrudApiPlugin replace JSONPath with JMESPath

[waldekmastykarz]

The .NET implementation of JSONPath is limited and only allows us to do basic filtering. In comparison, using JMESPath.net we can use the full power of JMESPath including implementing more complex scenarios such as paging ($top) or changing shape of the response ($select).

Let's switch to JMESPath and update the documentation accordingly.
