Add search filtering to Users admin index

[Hazmit]

Need to add a search filter to the users admin index page. Should be able to search by basic criteria such as, name, email, phone numbers.

Would be nice as a bonus to add in:

• Filter by special status flags such as "new_curler"
• Filter by members who do or do not have an active membership
• Filter by members duration of being members

This has been done, new filter options available and pagination as well as a search.
