Unnecessary api call to /rest/api/2/field

[aneeshco]

Bug summary

When doing api call using search_issues, it makes two API calls, one GET to the endpoint /rest/api/2/field and another to the actual url /rest/api/2/search. The first api call, returns the whole fields present in the JIRA server environment causing performance issues in the server. This is only done once the first time the function is used. Can this function be updated so that only the /rest/api/2/search is accessed?

issues_page = jira.search_issues(
jql_query,
startAt=start_at,
maxResults=MAX_RESULTS,
validate_query=False,
fields=fields_arg,
expand=None,
properties=None,
use_post=True)

Is there an existing issue for this?

Reproduction steps

# 1. Given a Jira client instance
jira: JIRA
# 2. When I call the function with below arguments 
issues_page = jira.search_issues(
                jql_query, 
                startAt=start_at, 
                maxResults=MAX_RESULTS,
                validate_query=False,
                fields=fields_arg,
                expand=None,
                properties=None,
                use_post=True)
# 3. It first calls the field endpoint and then it calls the search endpoint the first time, subsequent times doesnot include calls to field endpoint
# 4. It should only call the search endpoint and not the field endpoint
