title: Get vCPU count for a given AWS instance type in Go using AWS client
body: <p>I've the AWS instance type(e.g. <code>c5.18xlarge</code> etc.) in my config files. During runtime, I would like to fetch the number of vCPUs(e.g. <code>72</code>) from here: <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cpu-options-supported-instances-values.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cpu-options-supported-instances-values.html</a> and do some computations and launch instances based on the number of vCPUs.
  I can store this data from the <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cpu-options-supported-instances-values.html" rel="nofollow noreferrer">webpage</a> in a map and refer the map, but is there a way to fetch this information from AWS using AWS go client?</p>
