Get user name from id and vice versa

[SSadaiyappan-NI]

For custom webapps and Jupyter notebooks, we often query the users to create a mapping of name of the user from the ID and replace the fields in the APIs. Like for example, created by, updated by, assigned to fields in work items, work order etc. For example, these usernames are needed to be displayed in nimble tables of custom webapps (similar to the pipes we have in Angular code base for SLE).

It would be helpful if we have some sort of utility which does this for python
