The ujson 2.0.x doesn't compatible with Orquesta

[userlocalhost]

The ujson library that orquesta uses major upgraded on Mar 8, 2020. But it doesn't compatible with current Orquesta.
(c.f. https://pypi.org/project/ujson/#history)

Following code is am example to confirm it.

from orquesta import conducting
from orquesta.specs import native as native_specs
from orquesta import statuses
from orquesta.utils import jsonify as json_util

wf_def = """
version: 1.0

vars:
  - xs:
    - fee

tasks:
  task1:
    with: <% ctx(xs) %>
    action: core.echo message=<% item() %>
"""

spec = native_specs.WorkflowSpec(wf_def)

conductor = conducting.WorkflowConductor(spec)
conductor.request_workflow_status(statuses.RUNNING)

actual_tasks = conductor.get_next_tasks()
json_util.deepcopy(actual_tasks)

Case of using ujson(v1.35)

Case of using ujson(v2.0.0)

Case of using ujson(v2.0.2 (current latest version))
