Mutli-processing runs of ap_pipe using the sqlite setting for Ppdb are running into the issue of timeouts when storing, assessing the database. This is a similar issue to what to was discovered in the previous sqlite, db backend. This ticket will add a timeout config to Ppdb that will allow this setting to be increased for both sqlite and other db options.
Additionally, Andy Salnikov stated that PpdbProtoVisits was not meant to be used in production, only his testing. As such I will remove this call from being used in ap_association.
