[Gluster-infra] add Manikandan-Selvaganesh to github glusterfs-debian team

[Kaleb S. KEITHLEY]

Hi,

I thought I had privs to do this myself, but I'm not seeing how to do it
atm.

Please add Manikandan (Manikandan-Selvaganesh) to glusterfs-debian team
members. Maybe add him to GlusterFS team too?

Thanks
