v0.43.0

add cpu_options to launch template @y3ti (#159)

## what

Add new variable cpu_options to specify CPU options for an Amazon EC2 instance

why

I need to disable Intel Hyper-Threading for instances created by AutoScaling Group. EC2 and Launch Template provides a CPU Options configuration that allows for:

• disable Intel Hyper-Threading Technology by setting threads_per_core to 1 (default is 2 which means that hyper threading is enabled)
• define cpu cores per instance (you might do this to potentially optimize the licensing costs of your software with an instance that has sufficient amounts of RAM for memory-intensive workloads but fewer CPU cores)
• enable AMD Secure Encrypted Virtualization-Secure Nested Paging (AMD SEV-SNP) - a CPU feature that provides the following properties like attestation and memory encryption
