This PR adds several new functionalities to make easier the usage of ResourceManager:
- Now resource manager logs when resources are exceeded are on ERROR instead of warning.
- The resources exceeded error now shows what kind of limit was reached and the scope.
- When there was no limit exceeded, we print a message for the user saying that limits are not exceeded anymore.
- Added `swarm limit all` command to show all set limits with the same format as `swarm stats all`
- Added `min-used-limit-perc` option to `swarm stats all` to only show stats that are above a specific percentage
- Simplify a lot default values.
- **Enable ResourceManager by default.**
Output example:

## Validation tests
- Accelerated DHT client runs with no errors when ResourceManager is active. No problems were observed.
- Running an attack with 200 connections and 1M streams using yamux protocol. Node was usable during the attack. With ResourceManager deactivated, the node was killed by the OS because of the amount of memory consumed.
- Actions done when the attack was active:
- Add files
- Force a reprovide
- Use the gateway to resolve an IPNS address.
It closes#9001
It closes#9351
It closes#9322
New multi-router configuration system based on https://hackmd.io/G1KRDEX5T3qyfoBMkIrBew#Methods
- Added a new routing type: "custom"
- Added specific struct types for different Routers (instead of map[string]interface{})
- Added `Duration` config type, to make easier time string parsing
- Added config documentation.
- Use the latest go-delegated-routing library version with GET support.
- Added changelog notes for this feature.
It:
- closes#9157
- closes#9079
- closes#9186
* Do not connect to external nodes on ipfs as a lib example.
It was causing some build timeouts error because CircleCI
was throttling WAN connections.
It closes#8956
* style: rename node vars
since this is example, this should make things easier to follow
Co-authored-by: Marcin Rataj <lidel@lidel.org>
* 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

* feat: build examples against released packages instead of using replace directives to refer to the parent repo
* ci: run examples against the latest (unreleased) version of go-ipfs
The code example for using IPFS as a library doesn't run unless indirect dependencies are updated:
```
$ go version
go version go1.17 linux/amd64
$ uname -a
Linux home 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux

Also, require go version 1.16, otherwise, example can fail under go
