fix: Remove view in sql lab from druid datasources

[etr2460]

SUMMARY

This bug was reported internally, when you try to view in sql lab from a druid datasource with the native druid connector, it causes a JS error in sql lab. However, I don't think you should be able to open a native druid datasource in sql lab at all, so i'm removing this functionality

TEST PLAN
