fluent-plugin-prometheus prometheus_tail_monitor does not refresh deleted/rotated files.

We are using tail plugin with "pos_file_compaction_interval" option. With this option pos_file is getting updated by removing all deleted tailed file information. We are using the prometheus_tail_monitor plugin to get the information of tailed files.

Issue: When the tailed files are getting deleted/rotated, even though the pos_file is updated, But metrics fluentd_tail_file_inode and fluentd_tail_file_position are not updated and still shows the information of deleted/rotated files. As a result of this the amount of data exposed by these metrics are increasing continuously.
