ETLPipelineSerializer contains 'Blazegraph' repo hardcoded

[aorumbayev]

The createGraphStoreConfig method had Blazegraph hardcoded. I had to modify it to have Virtuoso hardcoded, along with authenticaion, user and pass fields for our local instance. It worked inside docker-compose with vrituoso running inside docker-compose after applying this change.

I am not entirely familiar with discovery codebase, but is there a feature that would allow to pass which repository I want to use during sbt run ?

There is a couple of other hotfixes that we had to apply, please refer to commit history on lpapps_fixes branch for more details. @jirihelmich
