Environment Detection

[waahm7]

Description of changes: Adds new APIs to retrieve information about the current environment and some preconfigured configurations for some EC2 instances. Currently, the CPU and CPU group are not utilized, but will be in the future. NIC information and syncing between preconfigured and runtime information are left as a to-do. Output on trn1n.32xlarge:

{
    'instance_type': 'trn1n.32xlarge',
    'max_throughput_gbps': 800,
    'has_recommended_configuration': true,
    'cpu_groups': [
    {
        'cpu_group_index': 0,
        'cpus_in_group': 64,
        'usable_network_devices': [
        ]
    },
    {
        'cpu_group_index': 1,
        'cpus_in_group': 64,
        'usable_network_devices': [
        ]
    }
    ]
}

Output on c5n.18xlarge:

{
    'instance_type': 'c5n.18xlarge',
    'max_throughput_gbps': 100,
    'has_recommended_configuration': false,
    'cpu_groups': [
    {
        'cpu_group_index': 0,
        'cpus_in_group': 36,
        'usable_network_devices': [
        ]
    },
    {
        'cpu_group_index': 1,
        'cpus_in_group': 36,
        'usable_network_devices': [
        ]
    }
    ]
}

Output on t2.large:

{
    'instance_type': '',
    'max_throughput_gbps': 0,
    'has_recommended_configuration': false,
    'cpu_groups': [
    {
        'cpu_group_index': 0,
        'cpus_in_group': 2,
        'usable_network_devices': [
        ]
    }
    ]
}

Changes I made from Jonathan's changes:

• Changed acquire and release function
• Removed runtime sync stuff as a TODO for future PR
• rename header file from platform_info to compute_platform_info to keep it consistent.
• Fix lint and warnings
• remove loader from imds callback to simplify the code By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
