aws: introduce maximum instance lifetime in cluster

The maximum instance lifetime is an AWS only feature and specifies the
maximum amount of time (in seconds) that an instance can be in service
before it is terminated and replaced.
A common use case might be a requirement to replace your instances on a
schedule because of internal security policies or external compliance
controls.

+
+The maximum instance lifetime specifies the maximum amount of time (in go duration [format](https://pkg.go.dev/time#ParseDuration)) that an instance can be in service before it is terminated and replaced.
+A common use case might be a requirement to replace your instances on a schedule because of internal security policies or external compliance controls. 
+In other words, this feature helps you to put a bit of ephemerality in your cluster.
+You must specify a value of at least 24h (86,400 seconds). To clear a previously set value, specify a new value of 0.
+
+The following configuration enables a maximum instance lifetime to two days.
+
+```yaml
+spec:
+  maxInstanceLifetime: "48h"
