query-timeout-default and -max cannot be set - type error.

[traylenator]

Describe the Bug

Creating a file /opt/puppetlabs/puppetdb/conf.d/puppetdb.ini containing

[puppetdb]
query-timeout-default = 30

Results in puppetdb start up error.

`ERROR [p.t.internal] Error during service init!!!   clojure.lang.ExceptionInfo: Value does not match schema: {:query-timeout-default (not (instance? java.lang.String 30))}`

Trying to set it as a string "30" results in

`Configured query-timeout-default timeout must be non-negative number, not "\"300\""`

Expected Behavior

PuppetDB should start up and respect the timeout.

Steps to Reproduce

Steps to reproduce the behavior:

1. Install PuppetDB 8 get it running in a trivial configuration.
2. Configure a [puppetdb] section with query-timerout-default
3. Restart PuppetDB.

Environment

• Version puppetdb 8.7.0
• Platform java-1.8.0-openjdk

Additional Context

Configuration settings are here - https://www.puppet.com/docs/puppetdb/8/configure#query-timeout-default

Behaviour is exactly the same for the query-timeout-max parameter also.
