Add a member

Conventions
{text} :	replace {text} with specific content
(root):	WebService URL base
(type) :	uwnetid \| group \| dns \| eppn

The group_id can be a group name (cn) or a regid.
A set of members can be specified with a comma-separated list.

GWS tries to guess the type of identifier you enter. You may express the type specifically using a type preface.

For example, u:spud_123 is a UWNetID, whereas g:spud_123 is a group name.

200	Member(s) added
304	If-None-Match header matches group's ETag
401	Not authorizied
404	Group not found

The response will be 404 only if the group is not found. If one or members are not found the response will be 200 and a class="notfoundmembers" element will be included, containing one "notfoundmember" element for each bogus member.
```
  <span class="notfoundmembers">
    <span class="notfoundmember">member_id</span>
    ...
  </span>
```
The response always includes an ETag header, which can be used on subsequent GETs.
