MEDIUM: ssl: introduce the ckch instance structure

struct ckch_inst represents an instance of a certificate (ckch_node)
used in a bind_conf. Every sni_ctx created for 1 ckch_node in a
bind_conf are linked in this structure.

This patch allocate the ckch_inst for each bind_conf and inserts the
sni_ctx in its linked list.
