gplay device-tiers (device-targeting for tiered delivery)

gplay device-tiers manages device tier configs, the app-scoped configuration that drives tiered content delivery: which devices fall into which tier, so Play can serve different assets to high-end and low-end devices. Shared conventions are in gplay-cli-usage. The whole namespace is [experimental].

Immutable

A config is immutable: to change targeting, create a new one and point delivery at the new deviceTierConfigId; old configs stay. That is why create needs no --confirm. Outside the Edit lifecycle (no editId): gplay edits begin does not batch it.
