Adding parameters in Env schema to support HashiCorp and CyberArk vaults

Testing

Successfully tested with HashiCorp vault
Successfully added CyberArk vault but could not test end-to-end since its host certificate expired on 4/28/2022. Since it simply has 1 string parameter "cyberark_query_string", I don't see any schema level error. This will be tested once the certificate of the test vault is renewed.
