Cronjob monitoring

[dereuromark]

I wonder if cronjob/queue monitoring could be useful, as per
https://docs.sentry.io/platforms/php/crons/

Sentry is initialized in https://github.com/LordSimal/cakephp-sentry/blob/3.x/src/CakeSentryInit.php#L43
which is called while bootstrapping the plugin https://github.com/LordSimal/cakephp-sentry/blob/3.x/config/bootstrap.php#L14

so in the end all a user has to do is call the namespaced functions from the PHP SDK and it should be fine.

We could add a Command.beforeExecute and Command.afterExecte event to the CommandRunner to at least capture the check-ins for before the command is started and after it has finished.

The heartbeat must be implemented by each command though I guess.
