+summary: Add a flag to skip audit/unenroll call to fleet server during uninstall

+# Long description; in case the summary is not enough to describe the change
+# this field accommodate a description without length limits.
+# NOTE: This field will be rendered only for breaking-change and known-issue kinds at the moment.
+description: This change adds a flag to skip audit/unenroll call to fleet server. While uninstalling elastic-agent it tries to notify fleet server about the uninstallation. But in somecases users might know that the fleet server is unreachable and this notification logs multiple failures continuously. Adding this flag skips this call.
