[SSSD] [PATCH] Keep sysdb context in domain info struct

Hi,
a few days ago I send a draft patch where the sysdb context is stored
in the domain info struct. I created a patch which is a bot more
conservative than the last one and included the comments by Simo (added
a destructor and don't unconditionally add the context all the time).
This patch will make the handling of sub-domains much easier, because
now only the domain info struct for the sub-domains needs to be
up-to-date.
bye,
Sumit
