Motivation:
`RedisKeyLifetime` already has "RedisKey" as a prefix so it naturally fits as a nested type.
Modifications:
- Change: `RedisKeyLifetime` to be nested in `RedisKey` and named `Lifetime`
- Rename: `RedisKeyLifetime.Lifetime` to `Duration`
- Deprecate: `RedisKeyLifetime` and the nested type `Lifetime`
Result:
The global namespace is a little less cluttered with the types falling naturally where they already are.
Motivation:
The TTL and PTTL commands are missing.
Modifications:
- Add TTL and PTTL commands
- Add integration tests
Result:
- Users can query the ttl in seconds or milliseconds of a key
