Daniel Nephin b2f49279e2 ca: split Primary/Secondary Provider
To make it more clear which methods are necessary for each scenario. This can
also prevent problems which force all DCs to use the same Vault instance, which
is currently a problem.

Daniel Nephin fc14f5ab14 ca: move provider creation into CAManager
This further decouples the CAManager from Server. It reduces the interface between them and
removes the need for the SetLogger method on providers.

Daniel Nephin f52d76f096 ca: replace ca.PrimaryIntermediateProviders
With an optional interface that providers can use to indicate if they
use an intermediate cert in the primary DC.

This removes the need to look up the provider config when renewing the
intermediate.

Ensure that CA initialization does not block leader election.
After fixing that bug I uncovered a couple more:

Fix an issue where we might try to cross sign a cert when we never had a valid root.
Fix a potential issue where reconfiguring the CA could cause either the Vault or AWS PCA CA providers to delete resources that are still required by the new incarnation of the CA.

Change CA Configure struct to pass Datacenter through (#6775)
* Change CA Configure struct to pass Datacenter through

* Remove connect/ca/plugin as we don't have immediate plans to use it.

We still intend to one day but there are likely to be several changes to the CA provider interface before we do so it's better to rebuild from history when we do that work properly.

* Rename PrimaryDC; fix endpoint in secondary DCs

Mitchell Hashimoto f76022fa63 CA Provider Plugins (#4751)
This adds the `agent/connect/ca/plugin` library for consuming/serving Connect CA providers as [go-plugin](https://github.com/hashicorp/go-plugin) plugins. This **does not** wire this up in any way to Consul itself, so this will not enable using these plugins yet. 

## Why?

We want to enable CA providers to be pluggable without modifying Consul so that any CA or PKI system can potentially back the Connect certificates. This CA system may also be used in the future for easier bootstrapping and internal cluster security.

### go-plugin

The benefit of `go-plugin` is that for the plugin consumer, the fact that the interface implementation is communicating over multi-process RPC is invisible. Internals of Consul will continue to just use `ca.Provider` interface implementations as if they're local. For plugin _authors_, they simply have to implement the interface. The network/transport/process management issues are handled by go-plugin itself.

The CA provider plugins support both `net/rpc` and gRPC transports. This enables easy authoring in any language. go-plugin handles the actual protocol handshake and connection. This is just a feature of go-plugin. 

`go-plugin` is already in production use for years by Packer, Terraform, Nomad, Vault, and Sentinel. We've shown stability for both desktop and server-side software. It is very mature.

## Implementation Details

### `map[string]interface{}`

The `Configure` method passes a `map[string]interface{}`. This map contains only Go primitives and containers of primitives (no funcs, chans, etc.). For `net/rpc` we encode as-is using Gob. For gRPC we marshal to JSON and transmit as a `bytes` type. This is the same approach we take with Vault and other software.

Note that this is just the transport protocol, the end software views it fully decoded.

### `x509.Certificate` and `CertificateRequest`

We transmit the raw ASN.1  bytes and decode on the other side. Unit tests are verifying we get the same cert/csrs across the wire.

### Testing

`go-plugin` exposes test helpers that enable testing the full plugin RPC over real loopback network connections. We test all endpoints for success and error for both `net/rpc` and gRPC.

### Vendoring

This PR doesn't introduce vendoring for two reasons:

  1. @banks's `f-envoy` branch introduces a lot of these and I didn't want conflict.
  2. The library isn't actually used yet so it doesn't introduce compile-time errors (it does introduce test errors).

## Next Steps

With this in place, we need to figure out the proper way to actually hook these up to Consul, load them, etc. This discussion can happen elsewhere, since regardless of approach this plugin library implementation is the exact same.
