add systemd support

Update go-libp2p-http (and go-libp2p-gostream)

feat: add ipfs version info to prometheus metrics

Adds `ipfs_info` prometheus metric with version and commit info

```prometheus
ipfs_info{commit="9ea7c6a1-dirty",version="0.5.0-dev"} 1
```

This follows the same pattern as go and other systems, adding a gauge metric that is set to 1, with the version info addeds as labels.

This is a common pattern for prometheus. It lets operators merge version info into other prometheus metrics by multiplying it with the other stat, as described in https://www.robustperception.io/exposing-the-software-version-to-prometheus

For example, we already expose the go version info as

```prometheus
go_info{version="go1.12.9"} 1
```

Fix typo

Manually removed some newly-appeared // indirect imports as
they seem to just pollute the go.mod.

That way, we can reliably know when the daemon is ready.

Instead of letting systemd override the configured addresses, merge them. This
is likely the "expected" behavior.

chore(dep): update everything

* multiaddr (fixes issues when the latest go-multiaddr is imported)
* libp2p (lots of fixes)
* prometheus
* gogo/protobuf

fixes #6676

github: migrate actions

Add bridged chats

doc(config): improve DisableNatPortMap documentation

plugins: support Close() for Tracer plugins as well

fix: make collect-profiles.sh work on mac

With an empty API headers config like

```js
	"API": {
		"HTTPHeaders": {}
	},
```

running collect-profiles.sh shows connection errors when trying to POST to `/debug/pprof-mutex/` end point when using `localhost`.

The same errors do not occur when using `127.0.0.1`

The version of `date` that ships with darwin does not support the `-Iseconds` flag.

Use a pattern with `date` to achieve the same thing but should have better cross platform support.

Most of the tracers available need to properly close to send
the remaining traces before the process exit.

namesys(test): test TTL on publish

No fix is complete without a test.

fixes #6670

pin: fix pin update X Y where X==Y

We were pining Y then removing the pin for X. When X == Y, we'd remove the new
pin.
