Function Add-InstanceProfile
{
    <#
            .SYNOPSIS
            Registers an instance profile in Databricks. In the UI, you can then give users the permission to use this instance profile when launching clusters.
            .DESCRIPTION
            Registers an instance profile in Databricks. In the UI, you can then give users the permission to use this instance profile when launching clusters.
            Official API Documentation: https://docs.databricks.com/api/latest/instance-profiles.html#profiles-add
            .PARAMETER InstanceProfileARN
            The AWS ARN of the instance profile to register with Databricks. It should look like: arn:aws:iam::<account-id>:instance-profile/<name>. This field is required.
            .PARAMETER SkipValidation
            By default, Databricks validates that it has sufficient permissions to launch instances with the instance profile. This validation uses AWS dry-run mode for the RunInstances API. If validation fails with an error message that does not indicate an IAM related permission issue, (e.g. "Your requested instance type is not supported in your requested Availability Zone"), you may pass this flag to skip the validation and forcibly add the instance profile.
            .EXAMPLE
            Add-DatabricksInstanceProfile -InstanceProfileARN "arn:aws:iam::123456789:instance-profile/datascience-role" -SkipValidation
