modified OCAccountManager APIs

modified OCAccountManager APIs

modified some APIs on OCAccountManager since the OCF cloud specification
has been changed.
(C++/Android API, sampleApp and unittest are modified)

- added a string parameter for accessToken on signOut() and deleteDevice().
- removed AclGroupType for createGroup() and added new overloaded one
  that has a map parameter for optional property values.
- changed getGroupList() to getGroupInfoAll() because it does not get a
  list anymore but information of all my group from account server.
- removed joinGroup(), deleteInvitation() and added replyToInvitation().
- removed addDeviceToGroup(), deleteDeviceFromGroup(), leaveGroup() and
  added addPropertyValueToGroup(), deletePropertyValueFromGroup(),
  updatePropertyValueOnGroup().
