Moved update of DNA plugin among update plugins

To make the code more general, moved the update_dna_shared_config
among other update plugins.

Bugfix: DNA shared config connection protocol was compared to a
method string which would result in a try to always update it
even if there was no need to.

https://fedorahosted.org/389/ticket/48373 causes that two
shared DNA config entries are created instead of one.
