Bug#865767: RM: rt-extension-sla -- ROM; obsoleted by RT 4.4

[Dominic Hargreaves]

Package: ftp.debian.org
Severity: normal

As per #851986 and #864276 this package is not useful any more.
Whilst unofficial backports may still be useful for jessie, this
doesn't benefit from the package being in sid.

Thanks,
Dominic.
