* A number of Mistral REST API endpoints support parameters that
allow to filter colections. For example, we can pass
do 'GET /v2/actions?name=in:std.' in a query string and Mistral
will return only actions containing 'std.' in their name.
This capability was missing in the client APIs, this patch
adds corresponding parameters in the APIs for actions,
workflows, executions (workflow executions) and tasks (task
executions).
TODO:
- Add required tests
