Membership policy update - decline application.

[Mathias Gug]

Hi,

I've added a section about declining membership application for the
launchpad team:

  Users that have applied for membership and have not met the criteria
  within a 4 month period will have their application declined.

When an application is declined, the following message should be sent:

  Hello,

  Thank you for your interest in the Ubuntu Server Team on Launchpad.
  We're sorry to decline your application as you haven't met the criteria
  to become a member.

  The Membership policy is outlined here:
  https://wiki.ubuntu.com/ServerTeam/Membership. 

  You can reapply for membership whenever you want by following the
  process described here:
  https://wiki.ubuntu.com/ServerTeam/GettingInvolved#becomemember.

  Thank you,

  The Ubuntu Server Team.

Everything is documented in the Membership wiki page:
https://wiki.ubuntu.com/ServerTeam/Membership

Thank you,
