r21135: Instead of having hooks to update keytabs as an explicit thing, update
them as a hook on ldb modify, via a module. This should allow the secrets.ldb to be edited by the admin, and to have things update in the on-disk keytab just as an in-memory keytab would. This isn't really a dsdb plugin, but I don't have any other good ideas about where to put it. Andrew Bartlett (This used to be commit 6ce557a1aff4754d2622be8f1c6695d9ee788d54)
