Query Workbench caches queries in localstorage

Queries in the query workbench are stored unencrypted and not user identity specifically in browser localstorage and not cleared. This is a potential security risk. Localstorage persists independently of Couchbase.

For Example:

[key]
CouchbaseQueryWorkbenchState_localhost:8091

[value]
{"pastQueries":[{"status":"cached query","resultCount":"0","resultSize":"0","result":"

{\"data_not_cached\": \"hit execute to rerun query\"}

{"data_not_cached":"hit execute to rerun query"}
