Add filters and sorters for sorting and filtering users

Description

As the number of contributors is growing and it’s quite hard to find one’s own profile, we need a feature to sort and filter out users. It is to be done on the client-side. The filterable fields are:

1. Github user name
2. User name
3. Country

The sortable fields are:

1. Country
2. Github user name
3. User name
4. Total commits (this year)
5. Followers

Acceptance criteria

• The above-listed fields should be filterable and sortable as listed.
• The filtering should be done on the client-side. (All the contributor data is present in UI as JSON)
• Add form fields to filter and sort.
