Create a mentors section

[abishekvashok]

We just added a new template
Create a mentors section in the current template with the same design.

The goal would be to create a mentor section, add a mentors.yml file, define a standard format, and make a mentor appear beautifully in the site using Jekyll.

note: be sure to ask mentors before posting any of their details
