Fix update_dna_shared_config to wait for both entries
update_dna_shared_config plugin now waits for presence of both
``dnaHostname=fqdn+dnaPortNum=0`` and
``dnaHostname=fqdn+dnaPortNum=389`` entries before it updates the
entries.
The commit also refactors the code of update_dna_shared_config for
subordinate id support.
