Add `YearlyPartitionsDefinition`

While at it, let's also have QuarterlyPartitionDefinition

The alternative is for users to use StaticPartitionDefinition (or Dynamic) which looses some of the benefits of a time-based partition.

I think the better alternative is to use TimeWindowPartitionsDefinition and specify the cron_schedule parameter as needed, for example:

quarterly_partitions_def = TimeWindowPartitionsDefinition(
    start=datetime(2015, 1, 1),
    cron_schedule="0 0 1 */3 *",
    fmt="%Y-%m")

half_year_partitions_def = TimeWindowPartitionsDefinition(
    start=datetime(2015, 1, 1),
    cron_schedule="0 0 1 */6 *",
    fmt="%Y-%m")

yearly_partitions_def = TimeWindowPartitionsDefinition(
    start=datetime(2015, 1, 1),
    cron_schedule="0 0 1 1 *",
    fmt="%Y")

At least that's what I've been using so far, and seems to have worked fine.
