Add runtime status/control of logging (#419)

- Feature: New endpoint `/admin/logs` to query status of logging and log file locations and cache logging
  - `enablewritelog`=`true`/`false` parameter to control cache write logging
  - `enableaccesslog`=`true`/`false` parameter to control cache access logging
  - `loglevel` = `trace`/`debug`/`info`/`warning`/`error`
- Feature: New zen command `logs` to query/control zen logging
  - No arguments gives status of logging and paths to log files
  - `--cache-write-log` `enable`/`disable` to control cache write logging
  - `--cache-access-log` `enable`/`disable` to control cache access logging
  - `--loglevel` `trace`/`debug`/`info`/`warning`/`error` to set debug level
