Description

If number of users are more than 20 then it shows only 20 users list. for other user it shows as not present.

Steps to reproduce:
1. Create more than 20 users in Ambari

2. Go to File views and start typing the random username under 'Grant permission to these users' - for some it show red mark when try to save it.

Root cause:
UI is making REST API call to load only 20 users

http://172.25.33.6:8080/api/v1/users?Users/user_name.matches(.*.*)&from=0&page_size=20&_=1545350079963

so Ambari is returning 20 users and rest of them will not shown in views grant page.
