Issue Summary

In this API https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-user-search/#api-rest-api-3-user-picker-get: 
It is only possible to filter out Jira users from the response, however, this resource is not paginated and results are limited to 100 items, which implies it is not feasible to filter out all Jira users in some cases, for example when an instance has many customers. There should be some sort of flag to exclude accountType==="customer".

Feature request is to add a request parameter accountType that when passed, excludes other account types for returned users.

Steps to Reproduce

Using this endpoint https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-user-search/#api-rest-api-3-user-picker-get there is no possibility to filter results by accountType

Expected Results

Adding the possibility of to use accountType as a parameter in the payload to filter the results. 

Actual Results

Lack of accountType parameter.

Workaround

No workaround.
