Able to get Box user ID by querying the username
Hi, currently in order to find a box user id for ONE user, we need to use
https://developer.box.com/reference#get-all-users-in-an-enterprise
to get ALL users and then filter for the specific user.
If would be nice if we can simply query a user's box user id by the username.

There is an optional parameter called `filter_term` which can be used to retrieve a user on the basis of the name or login. See link below and a snippet from the dev docs.
https://developer.box.com/reference/get-users/#param-filter_term
`filter_term`
Limits the results to only users who’s name or login start with the search term.
For externally managed users, the search term needs to completely match the in order to find the user, and it will only return one user at a time.
