Allow common redis and leveldb connections (#12385)

* Allow common redis and leveldb connections

Prevents multiple reopening of redis and leveldb connections to the same
place by sharing connections.

Further allows for more configurable redis connection type using the
redisURI and a leveldbURI scheme.

# Changelog
## Unreleased
- Cluster and Ring pipelines process commands for each node in its own goroutine.
## 6.14
- Added Options.MinIdleConns.
- Added Options.MaxConnAge.
- PoolStats.FreeConns is renamed to PoolStats.IdleConns.
- Add Client.Do to simplify creating custom commands.
- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
- Lower memory usage.
## v6.13
- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set `HashReplicas = 1000` for better keys distribution between shards.
- Cluster client was optimized to use much less memory when reloading cluster state.
- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.
- Dialer.KeepAlive is set to 5 minutes by default.
## v6.12
- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup
