filter_aws: add more IMDS categories

[commiterate]

Add more IMDS categories.

Excluding the EC2 Auto Scaling target lifecycle state (autoscaling/target-lifecycle-state) from the feature request since the AWS filter seems to assume that IMDS data is immutable. We can just make the process that polls it log the state to stdout (for systemd-journald) or syslog to correlate on-system events.

Note that dedicated host ID (and other metadata, both existing and new) may also be mutable due to live migration.

When a degradation is detected on a Dedicated Host that is enabled for host maintenance, we automatically allocate a replacement Dedicated Host in your account. The replacement Dedicated Host receives a new host ID, but retains the same attributes as the original Dedicated Host, including:

• Auto placement settings
• Availability Zone
• Dedicated Host Reservation association
• Host affinity
• Host maintenance settings
• Host recovery settings
• Instance type
• Tags

Once the replacement host has been allocated, we migrate the instances using either live migration host maintenance or reboot-based host maintenance, depending on the instance.
