feat: go-libp2p 0.16, UnixFS autosharding and go-datastore with contexts (#8563)

* plumb through go-datastore context changes * update go-libp2p to v0.16.0 * use LIBP2P_TCP_REUSEPORT instead of IPFS_REUSEPORT * use relay config * making deprecation notice match the go-ipfs-config key * docs(config): circuit relay v2 * docs(config): fix links and headers * feat(config): Internal.Libp2pForceReachability This switches to config that supports setting and reading Internal.Libp2pForceReachability OptionalString flag * use configuration option for static relays * chore: go-ipfs-config v0.18.0 https://github.com/ipfs/go-ipfs-config/releases/tag/v0.18.0 * feat: circuit v1 migration prompt when Swarm.EnableRelayHop is set (#8559) * exit when Swarm.EnableRelayHop is set * docs: Experimental.ShardingEnabled migration This ensures existing users of global sharding experiment get notified that the flag no longer works + that autosharding happens automatically. For people who NEED to keep the old behavior (eg. have no time to migrate today) there is a note about restoring it with `UnixFSShardingSizeThreshold`. * chore: add dag-jose code to the cid command output * add support for setting automatic unixfs sharding threshold from the config * test: have tests use low cutoff for sharding to mimic old behavior * test: change error message to match the current error * test: Add automatic sharding/unsharding tests (#8547) * test: refactored naming in the sharding sharness tests to make more sense * ci: set interop test executor to convenience image for Go1.16 + Node * ci: use interop master Co-authored-by: Marcin Rataj <lidel@lidel.org> Co-authored-by: Marten Seemann <martenseemann@gmail.com> Co-authored-by: Marcin Rataj <lidel@lidel.org> Co-authored-by: Gus Eggert <gus@gus.dev> Co-authored-by: Lucas Molas <schomatis@gmail.com>

-#### Mode 1: `EnableRelayHop` is `false`

-If `Swarm.EnableAutoRelay` is enabled and `Swarm.EnableRelayHop` is disabled,
-your node will automatically _use_ public relays from the network if it detects
-that it cannot be reached from the public internet (e.g., it's behind a

-
-If you enable `EnableAutoRelay`, you should almost certainly disable
-`EnableRelayHop`.
-
-#### Mode 2: `EnableRelayHop` is `true`
-
-If `EnableAutoRelay` is enabled and `EnableRelayHop` is enabled, your node will
-_act_ as a public relay for the network. Furthermore, in addition to simply
-relaying traffic, your node will advertise itself as a public relay. Unless you
-have the bandwidth of a small ISP, do not enable both of these options at the
-same time.

 ## Directory Sharding / HAMT

 ### In Version
-0.4.8
+
+- 0.4.8:
+  - Introduced `Experimental.ShardingEnabled` which enabled sharding globally.
+  - All-or-nothing, unnecessary sharding of small directories.
+
+- 0.11.0 :
+  - Removed support for `Experimental.ShardingEnabled`
+  - Replaced with automatic sharding based on the block size

 ### State
-Experimental

-Allows creating directories with an unlimited number of entries.
+Replaced by autosharding.

-**Caveats:**
-1. right now it is a GLOBAL FLAG which will impact the final CID of all directories produced by `ipfs.add` (even the small ones)
-2. currently size of unixfs directories is limited by the maximum block size
+The `Experimental.ShardingEnabled` config field is no longer used, please remove it from your configs.

-### Basic Usage:
-
-```
-ipfs config --json Experimental.ShardingEnabled true

-### Road to being a real feature
-
- [ ] Make sure that objects that don't have to be sharded aren't
- [ ] Generalize sharding and define a new layer between IPLD and IPFS
+go-ipfs now automatically shards when directory block is bigger than 256KB, ensuring every block is small enough to be exchanged with other peers

 Modify your ipfs config:

+ipfs config --json Swarm.RelayClient.Enabled true
 ```

-NOTE: Ensuring `Swarm.EnableRelayHop` is _false_ is extremely important here. If you set it to true, you will _act_ as a public relay for the rest of the network instead of _using_ the public relays.
