[FEATURE] Add additional features to compute nodes

[cartalla]

Is your feature request related to a problem? Please describe. This is an example of a node definition from ParallelCluster:

NodeName=od-16-gb-dy-od-16gb-1-cores-[1-1000] CPUs=1 RealMemory=15564 State=CLOUD Feature=dynamic,od-16gb-1-cores Weight=1363

NodeName=od-128-gb-dy-od-128gb-2-cores-[1-1000] CPUs=2 RealMemory=124518 State=CLOUD Feature=dynamic,x2iedn.xlarge,od-128gb-2-cores Weight=8336

This is from my legacy Slurm cluster:

NodeName=use1-az4-m8-arm-c6g-m-sp-[0-4]          CPUs=1  RealMemory=1328    Feature=us-east-1a,use1-az4,m8,AlmaLinux_8,arm64,c6g,c6g.medium,GHz:2.5,spot                                    Weight=325

Describe the solution you'd like Add the following features to ParallelCluster nodes:

• spot, ondemand
• AZ
• OS
• CPU architecture
• Instance families
• Instance types
• CPU freq
• Amount of ephemeral SSD

It appears that the instance type is included if there is only 1 instance type in the compute resource. Would it make sense to include all configured instance types.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
