## What changes were proposed in this pull request?
SCM Pipeline Add `supportedStorageTier` Field
- Set `supportedStorageTier` for Pipeline when the Pipeline be created
- Pipeline can support zero or more different types of `StorageTier`,
depending on the Volume `StorageType` of the Datanodes that make up the
Pipeline.
- For example, if the three Datanodes of a 3 replica Pipeline have SSD and
DISK `StorageType` Volumes, then the Pipeline `supportedStorageTier` is
`StorageTier.SSD` and `StorageTier.DISK`
- The `supportedStorageTier` by the Pipeline is not fixed. This field will
be set when the Pipeline is created and will be updated in the
`PipelineReportHandler` and `NodeReportHandler`.
- When the `StorageType` of the Volume of the Datanode in the Pipeline
changes (for example, the Datanode configuration is manually modified), the
`supportedStorageTier` of the Pipeline will also change
