bugfix/flagging issue

[brucehyslop]

changed the isUnderCas variable to isUnderAuth and configure based on either CAS or OIDC being enabled.

The flag item bug was caused by the isUnderCas JS property being set from a string without surrounding quote characters. This resulted in an invalid JS object which caused functions in show.js fail to register jQuery handlers to process the "flag item" submit event. https://github.com/AtlasOfLivingAustralia/biocache-hubs/blob/224c40b1a6035a4b44b276f2bcf090643a2d8157/grails-app/views/occurrence/show.gsp#L56

updated extragrailsApplication.config.getProperty() method

• [x] Changes here look good. Can submit assertions now . I've not noticed that the assertions deletions encounters a 405 errors. This appears to be due to the the deleteAssertions functional calling a DELETE method on /occurrences/${recordUuid}/assertions/${assertionUuid} which does not exist on biocache-service for the DELETE method. We will have to switch over to /occurrences/{recordUuid}/assertions/delete with a body param or /occurrences/assertions/delete with both prams in the body if using the DELETE method
