method parameters_for_path does not check for `next_token`

[ashleygould]

If more than MaxResults params are available, this method will fail to retrieve all parameters.

See get_parameters_by_path documentation in https://github.com/aws/aws-sdk-ruby/blob/master/gems/aws-sdk-ssm/lib/aws-sdk-ssm/client.rb (starting at line 5911)

Also: https://docs.aws.amazon.com/sdk-for-ruby/v2/api/Aws/SSM/Client.html#get_parameters_by_path-instance_method

Frankly, in it's current form I see no reason to include this method in the gem.

For it to be useful, it should by default do decryption and recursive lookup. And it should format it's out put as a array of simple name,value hashes. path should be a positional parameter, options a second positional parameter. This would allow user to override recursion or decryption, or add search filters, but not alter next_token behavior.

example:

myResolver.parameters_for_path("mykey", {recursive: false})

# returns
[{
  /root/path/mykey/thing1 => 'blee',
  /root/path/mykey/thing2 => 'glee'
}]

This was ported from the Java code. The java code does do this recursively.
