// Creates a log group with the specified name. You can create up to 1,000,000 log
// groups per Region per account. You must use the following guidelines when naming
// a log group:
//   - Log group names must be unique within a Region for an Amazon Web Services
//     account.
//   - Log group names can be between 1 and 512 characters long.
//   - Log group names consist of the following characters: a-z, A-Z, 0-9, '_'
//     (underscore), '-' (hyphen), '/' (forward slash), '.' (period), and '#' (number
//     sign)
//   - Log group names can't start with the string aws/
//
// When you create a log group, by default the log events in the log group do not
// expire. To set a retention policy so that events expire and are deleted after a
// specified time, use PutRetentionPolicy (https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_PutRetentionPolicy.html)
// . If you associate an KMS key with the log group, ingested data is encrypted
// using the KMS key. This association is stored as long as the data encrypted with
// the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to
// decrypt this data whenever it is requested. If you attempt to associate a KMS
// key with the log group but the KMS key does not exist or the KMS key is
// disabled, you receive an InvalidParameterException error. CloudWatch Logs
// supports only symmetric KMS keys. Do not associate an asymmetric KMS key with
// your log group. For more information, see Using Symmetric and Asymmetric Keys (https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html)
