Related Language Python

To Reproduce Steps to reproduce the behavior:

1. Start recorder
2. From EC2 Dashboard click Launch Instance
3. Select default amazon linux 2 ami
4. Select default t2.micro instance type
5. Change default VPC/subnet to anything else.
6. Next, Next, Next
7. On security group setup page, choose any existing security group.
8. Next next finish through wizard

Expected behavior boto3 ec2 client run_instances() argument is "BlockDeviceMappings" (see https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ec2.html#EC2.Client.run_instances). Recorder is currently outputting "BlockDeviceMapping".

For example:

response = ec2_client.run_instances(
    ImageId='ami-009d6802948d06e52',
    MaxCount=1,
    MinCount=1,
    KeyName='mykey',
    InstanceType='t2.micro',
    Placement={
        Tenancy='default'
    },
    Monitoring={
        Enabled=False
    },
    DisableApiTermination=False,
    InstanceInitiatedShutdownBehavior='stop',
    CreditSpecification={
        CpuCredits='standard'
    },
    EbsOptimized=False,
    BlockDeviceMapping=[
        {
            DeviceName='/dev/xvda',
            Ebs={
                VolumeSize=8,
                DeleteOnTermination=True,
                VolumeType='gp2'
            }
        }
    ]
)
