Unity: update Unity REST 5.0.3 and 5.1.0 change (#320)

Unity 5.0.3 and 5.1.0 removed some deprecated fields of resources.
So, storops needs to add new fields to these resources if necessary.
Getting old fields will return `None` instead of raising
`AttributeError`. The client of storops needs to update to use new
fields.

1. `UnityHostInitiator`'s `source_type` is renamed to
`initiator_source_type`.
2. `UnityLinkAggregation`'s `parent_storage_processor` is renamed to
`storage_processor`.
3. `UnityLun`'s `is_compression_enabled` is renamed to
`is_data_reduction_enabled`.
4. Use `modification_time` to check if `UnitySnapSchedule` is modified
or not. `is_modified` is removed.
5. `UnitySystemCapacity`'s `compression_size_saved`/
`compression_percent`/`compression_ratio` is renamed to
`data_reduction_size_saved`/`data_reduction_percent`/
`data_reduction_ratio`.
6. No function/method argument needs to change.
