Update tags_spec for Kinesis.Stream (#122)
Update tags_spec for Kinesis.Stream (#122)

We can now retrieve Kinesis.Stream tag list.
Note: if boto3's documentation (http://boto3.readthedocs.io/en/latest/reference/services/kinesis.html#Kinesis.Client.list_tags_for_stream)
and AWS API's documentation (https://docs.aws.amazon.com/kinesis/latest/APIReference/API_ListTagsForStream.html)
the API call is described as having a "NextToken"-like mechanism implemented.
As far as I could see, skew's implementation relies on boto3's
can_paginate / get_paginator to handle this.
But it seems that boto3's latest version do not have a paginator
for the list_tags_for_stream() call.
I may have understood all this wrongly of course, but if it
were true, we *could* loose some of the tags.
