Add --health-max-log-count, --health-max-log-size, --health-log-destination flags
These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.
This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.
- The `--health-log-destination` flag sets the destination of the HealthCheck log.
- `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
- `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
- `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.
- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
- A value of `0` indicates an infinite number of attempts in the log file.
- The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
- A value of `0` indicates an infinite log length.
- The default value is `500` log characters.
