Optimize purview query for getting features

[enya-yx]

Description

Resolves #564

• Modify 'get_project_features' API to reduce time consuming
• Main idea is calling only one purview client API to avoid too many HTTP requests
• Performance comparison:
  Input
  start = time.time()
  features = registry.get_project_features("enya_test_registry")
  feature_list=list([to_camel(e.to_dict()) for e in features])
  print("duration1: ", time.time()-start)
  start = time.time()
  features = registry.get_project_features_origin("enya_test_registry")
  feature_list=list([to_camel(e.to_dict()) for e in features])
  print("duration2: ", time.time()-start)
  Output:
  duration1: 2.2548649311065674
  duration2: 16.783140897750854
