Christian Muehlhaeuser 2602f6907e Simplified code in various places (#6176)
All these changes should have no side-effects or change behavior:

- Use bytes.Buffer's String() instead of a conversion
- Use time.Since and time.Until where fitting
- Drop unnecessary returns and assignment

Mitchell Hashimoto 5452c32f50 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.

Aestek 260a9880ae [Security] Add finer control over script checks (#4715)
* Add -enable-local-script-checks options

These options allow for a finer control over when script checks are enabled by
giving the option to only allow them when they are declared from the local
file system.

* Add documentation for the new option

Fix CA pruning when CA config uses string durations. (#4669)
* Fix CA pruning when CA config uses string durations.

The tl;dr here is:

 - Configuring LeafCertTTL with a string like "72h" is how we do it by default and should be supported
 - Most of our tests managed to escape this by defining them as time.Duration directly
 - Out actual default value is a string
 - Since this is stored in a map[string]interface{} config, when it is written to Raft it goes through a msgpack encode/decode cycle (even though it's written from server not over RPC).
 - msgpack decode leaves the string as a `[]uint8`
 - Some of our parsers required string and failed
 - So after 1 hour, a default configured server would throw an error about pruning old CAs
 - If a new CA was configured that set LeafCertTTL as a time.Duration, things might be OK after that, but if a new CA was just configured from config file, intialization would cause same issue but always fail still so would never prune the old CA.
 - Mostly this is just a janky error that got passed tests due to many levels of complicated encoding/decoding.

tl;dr of the tl;dr: Yay for type safety. Map[string]interface{} combined with msgpack always goes wrong but we somehow get bitten every time in a new way :D

We already fixed this once! The main CA config had the same problem so @kyhavlov already wrote the mapstructure DecodeHook that fixes it. It wasn't used in several places it needed to be and one of those is notw in `structs` which caused a dependency cycle so I've moved them.

This adds a whole new test thta explicitly tests the case that broke here. It also adds tests that would have failed in other places before (Consul and Vaul provider parsing functions). I'm not sure if they would ever be affected as it is now as we've not seen things broken with them but it seems better to explicitly test that and support it to not be bitten a third time!

* Typo fix

* Fix bad Uint8 usage

Matt Keeler b3ba709b3d Remove x509 name constraints
These were only added as SPIFFE intends to use the in the future but currently does not mandate their usage due to patch support in common TLS implementations and some ambiguity over how to use them with URI SAN certificates. We included them because until now everything seem fine with it, however we've found the latest version of `openssl` (1.1.0h) fails to validate our certificats if its enabled. LibreSSL as installed on OS X by default doesn’t have these issues. For now it's most compatible not to have them and later we can find ways to add constraints with wider compatibility testing.
