works around bug: dont add mergeable datasets to SearchOutputData (legacy response.xml would crash on mergeable dataset xml-print)

updates to pre-release of volib v0.9.0. And removes append POSSYS and BANDSYS to queryString build (is done in vlkb-volib POS and BAND toString)

includes vlkb-volib and modifies Coord to use volib/VO-params (Parser still recognizes VLKB-legacy params)

docker: consolidates docker build/configure and makes security conf the same as in vlkb-soda + example-security added now

config: adss DB-config to Format-filter (Search-servlet ahs its own config entry) and Db-search module is inited by Search-config or Format-config

adds ID=/pubdid= without value to merge/cutout-url so as url params are like input to seacrh (SIAv2 or VLKB-legacy)

modifies API recognition: VLKB-legacy only if 'l'&'b' params present in query string and synchronizes it with cutout/merge URL generation (VLKB-legacy or VO-Siav2)
