No valid waiter names for SSM API

[vanguard737]

In the v2 SDK, it appears that SSMs don't expose any valid waiters. If I throw a bogus waiter at (for example) the CloudFormation client, I get a well-formed exception with the list of valid CFN waiter names. However, when I do the same to the SSM client, I don't get any waiter names back.

This issue may be relevant. Perhaps this has been implemented for SSM in the latest v3 SDK (and not v2)?

Gem: aws-sdk, 2.9.26.
Environment: Ruby 2.4.1, Windows 10.

Code, run from irb:

require 'aws-sdk'
Aws.config.update({
    region: 'us-west-2',
    credentials: Aws::Credentials.new('AKIAid', 'secret')
})

cfn = Aws::CloudFormation::Client.new
cfn.wait_until(:bogus)

ssm = Aws::SSM::Client.new
ssm.wait_until(:bogus)

The respective exceptions:

CFN:

Aws::Waiters::Errors::NoSuchWaiterError: no such waiter :bogus; valid waiter names are: :stack_exists, :stack_create_complete, :stack_delete_complete, :stack_update_complete, :change_set_create_complete

Currently there is no waiter available for SSM, marking this as a feature request for adding waiters for SSM service.
