Adds one or more tags to a trail, up to a limit of 50. Tags must be unique per trail. Overwrites an existing tag's value when a new value is specified for an existing tag key. If you specify a key without a value, the tag will be created with the specified key and a value of null. You can tag a trail that applies to all regions only from the region in which the trail was created (that is, from its home region).
