hades hackathon enhancement for #538

@ob325 thank you so much for this contribution! It was wonderful meeting you at the hackathon and I really appreciate you following through on this PR 😄

I think the changes all look good. There are just 2 things left to do before we can merge this in:

• R CMD Check is throwing a warning because the docs need to be regenerated. If you run devtools::document() in the R console within the project, that should fix the warning
• It'd also be great to update our vignette with info about the new parameter. I'm thinking you could just add a couple lines here showing how to set the checkSeverity parameter, and add it to the executeDqChecks function call:

  DataQualityDashboard/vignettes/DataQualityDashboard.rmd

  Lines 112 to 133 in 98c825a

  	# which CDM tables to exclude? ------------------------------------
  	tablesToExclude <- c("CONCEPT", "VOCABULARY", "CONCEPT_ANCESTOR", "CONCEPT_RELATIONSHIP", "CONCEPT_CLASS", "CONCEPT_SYNONYM", "RELATIONSHIP", "DOMAIN") # list of CDM table names to skip evaluating checks against; by default DQD excludes the vocab tables
  	# run the job --------------------------------------------------------------------------------------
  	DataQualityDashboard::executeDqChecks(connectionDetails = connectionDetails,
  	cdmDatabaseSchema = cdmDatabaseSchema,
  	resultsDatabaseSchema = resultsDatabaseSchema,
  	cdmSourceName = cdmSourceName,
  	cdmVersion = cdmVersion,
  	numThreads = numThreads,
  	sqlOnly = sqlOnly,
  	sqlOnlyUnionCount = sqlOnlyUnionCount,
  	sqlOnlyIncrementalInsert = sqlOnlyIncrementalInsert,
  	outputFolder = outputFolder,
  	outputFile = outputFile,
  	verboseMode = verboseMode,
  	writeToTable = writeToTable,
  	writeToCsv = writeToCsv,
  	csvFile = csvFile,
  	checkLevels = checkLevels,
  	tablesToExclude = tablesToExclude,
  	checkNames = checkNames)

Let me know if those additions sound doable to you! Thanks again!
