generate a single debug file for a long duration capture (#10279)
* debug: remove the CLI check for debug_enabled

The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.

Also:
- fix the API client to return errors on non-200 status codes for debug
  endpoints
- improve the failure messages when pprof data can not be collected

Co-Authored-By: Dhia Ayachi <dhia@hashicorp.com>

* remove parallel test runs

parallel runs create a race condition that fail the debug tests

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* extract wait group outside the go routine to avoid a race condition

* capture pprof in a separate go routine

* perform a single capture for pprof data for the whole duration

* add missing vendor dependency

* add a change log and fix documentation to reflect the change

* create function for timestamp dir creation and simplify error handling

* use error groups and ticker to simplify interval capture loop

* Logs, profile and traces are captured for the full duration. Metrics, Heap and Go routines are captured every interval

* refactor Logs capture routine and add log capture specific test

* improve error reporting when log test fail

* change test duration to 1s

* make time parsing in log line more robust

* refactor log time format in a const

* test on log line empty the earliest possible and return

Add per-agent reconnect timeouts (#8781)
This allows for client agent to be run in a more stateless manner where they may be abruptly terminated and not expected to come back. If advertising a per-agent reconnect timeout using the advertise_reconnect_timeout configuration when that agent leaves, other agents will wait only that amount of time for the agent to come back before reaping it.

This has the advantageous side effect of causing servers to deregister the node/services/checks for that agent sooner than if the global reconnect_timeout was used.

add primary keys to list keyring (#8522)
During gossip encryption key rotation it would be nice to be able to see if all nodes are using the same key. This PR adds another field to the json response from `GET v1/operator/keyring` which lists the primary keys in use per dc. That way an operator can tell when a key was successfully setup as primary key.

Based on https://github.com/hashicorp/serf/pull/611 to add primary key to list keyring output:

```json
[
  {
    "WAN": true,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 6,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "NumNodes": 6
  },
  {
    "WAN": false,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 8,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  },
  {
    "WAN": false,
    "Datacenter": "dc1",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 3,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  }
]
```

I intentionally did not change the CLI output because I didn't find a good way of displaying this information. There are a couple of options that we could implement later:
* add a flag to show the primary keys
* add a flag to show json output

Fixes #3393.

Upgrade go-connlimit to v0.3.0 / return http 429 on too many connections (#8221)
Fixes #7527

I want to highlight this and explain what I think the implications are and make sure we are aware:

* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
  1) `conn.SetDeadline(10*time.Millisecond)` so that
  2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and 
  3) `conn.Close` can happen

The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.

Add a test for go routine leaks
This is in its own separate package so that it will be a separate test binary that runs thus isolating the go runtime from other tests and allowing accurate go routine leak checking.

This test would ideally use goleak.VerifyTestMain but that will fail 100% of the time due to some architectural things (blocking queries and net/rpc uncancellability).

This test is not comprehensive. We should enable/exercise more features and more cluster configurations. However its a start.

Daniel Nephin 221a49f430 Update protobuf and golang.org/x/... vendor
Partially extracted from #7547

Updates protobuf to the most recent in the 1.3.x series, and updates
golang.org/x/sys to a7d97aace0b0 because of https://github.com/shirou/gopsutil/issues/853
prevents updating to a more recent version.

This breaking change in x/sys also prevents us from getting a newer
version of x/net. In the future, if gopsutil is not patched,  we may want to run a fork version of
gopsutil so that we can update both x/net and x/sys.
