Exception: module 'collections' has no attribute 'Mapping' for python version 3.10

[indrajit0909]

Describe the bug I am using python version 3.10 and when I am trying to run the test cases for connectors like aws_athena, some test cases are failing. So when I debugged the code I found that lines 46 and 49 of file stix_shifter_utils/utils/error_response.py threw exception which stated module 'collections' has no attribute 'Mapping'. Also when I am trying to run execute command for few connectors I found a similar error on line 128 for file stix_shifter_utils/stix_transmission/utils/RestApiClient.py which stated stix_shifter_utils.stix_transmission.utils.RestApiClient ERROR exception occured during requesting url: module 'collections' has no attribute 'Mapping'.

To Reproduce Steps to reproduce the behavior:

1. Upgrade to python version 3.10
2. Run the execute cmd for any UDP connector
3. See error

Expected behavior The execute cmd should run successfully and the test cases should not fail

Additional context Below is the stack trace for execute command of UDP connector

Solution Changing collections.Mapping to collections.abc.Mapping fixes the issue. I have checked it with version 3.9 as well and the change works for it as well.

@indrajit0909 stix-shifter doesn't support python 3.10 yet. it will be addressed when we support 3.10.
