Support all documented retentionInDays values

[phs]

If we look in the cloudformation docs for the log group resource, we see these allowed values in the retentionInDays field:

The number of days to retain the log events in the specified log group. Possible values are: 1, 3, 5, 7, 14, 30, 60, 90, 120, 150, 180, 365, 400, 545, 731, 1827, 2192, 2557, 2922, 3288, and 3653.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-logs-loggroup.html

However when I try to use value 2557 in a cloudformation template, I get an error:

Model validation failed (#/RetentionInDays: #: only 1 subschema matches out of 2)
#/RetentionInDays: failed validation constraint for keyword [enum] (#/RetentionInDays)

If we look in the source to see the actual schema, we see (for example) that 2557 does not appear in the list.

	14,

	365,
	400,
	545,
	731,
	1827,
	3653
	]
	},

When I use the AWS console I can successfully choose 2557 (or rather, seven years). So it seems the schema in this repository is missing some entries.
