Allow disabling calico CNI logs with calico_cni_log_file_path (#8921)

Browse Source 
* Allow disabling calico CNI logs with calico_cni_log_file_path

Calico CNI logs up to 1G if it log a lot with current default settings:
log_file_max_size	100	Max file size in MB log files can reach before they are rotated.
log_file_max_age	30	Max age in days that old log files will be kept on the host before they are removed.
log_file_max_count	10	Max number of rotated log files allowed on the host before they are cleaned up.

See https://projectcalico.docs.tigera.io/reference/cni-plugin/configuration#logging

To save disk space, make the path configurable and allow disabling this log by setting
`calico_cni_log_file_path: false`

* Fix markdown

* Update roles/network_plugin/canal/templates/cni-canal.conflist.j2
