Implemented querying, this when used with the endpoint /run/:token will query the destination and reply with the raw unaltered response.
Fixed email and when a query has been executed a log is created.
Finished logs, querying the logs of a endpoint using its token will return all the log entries, an avg ms response time and the number of entries in that log.
Changed NO_CONTENT for CONFLICT
