	// DefaultEnforcerdCleanerPath is the default path of the cleaner.  For now set this to
	// /sbin/cleaner.  Note that the cleaner path is set via the container master enforcer but
	// it is ultimately run in the host and not in the container. Prior to defender integrations
	// we used the same path /sbin/cleaner in the host and /sbin/cleaner in the container and it
	// worked.  Now, with the defender integration we use a tarball to install the enforcer and
	// all the binaries, and it may install anywhere on the host, as specified by the defender
	// installer.  The container does not know where it was installed. Furthermore, we no longer
	// install via .deb or .rpm files so there is no system files installed, and cleaner will not
	// be found in /sbin/cleaner when installed via the defender bundle installer.  So a new
	// startup flag is defined now, `--cleaner-path` and environment variable
	// `ENFORCED_CLEANER_PATH` that defender can use to tell us where it installed the
	// cleaner. With this, the container enforcer can properly set the cleaner path in the
	// cgroups v1 release_agent.
	//
	// TLDR; We now use /enforcerd-tools/cleaner in the container, and it will be installed in
	// /path/to/install/ation/dir/enforcerd-tools/cleaner in the host.  container enforcer will
	// tell cgroup sub-system to use /enforcerd-tools/cleaner but cgroups executes it on the
	// host and can't find it here. Ergo, it won't work on a defender install this way.
	//
	// TODO - fix this so cleaner can be installed by defender and the installation path can be
	// discovered by container enforcer

	SynTokenRefreshTime = 5 * time.Minute
	// SynTokenValidity determines how long after the tokens are considered valid.
	SynTokenValidity = 10 * time.Minute
)

Token and cache default validities. These have performance implications. The faster the datapath issues new tokens it affects performance. However, making it too slow can potentially allow reuse of the tokens. The token issuance rate must be always faster than the expiration rate.

Mark used by the proxies/ping to bypass trap rules.
