Pierre Souchay 251156eb68 Added SOA configuration for DNS settings. (#4714)
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```
dig +multiline @localhost -p 8600 service.consul

Paul Banks b83bbf248c Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs

Paul Banks 88388d760d Support Agent Caching for Service Discovery Results (#4541)
* Add cache types for catalog/services and health/services and basic test that caching works

* Support non-blocking cache types with Cache-Control semantics.

* Update API docs to include caching info for every endpoint.

* Comment updates per PR feedback.

* Add note on caching to the 10,000 foot view on the architecture page to make the new data path more clear.

* Document prepared query staleness quirk and force all background requests to AllowStale so we can spread service discovery load across servers.

Hannah Oppenheimer 6b487f80ff Clarify enable_tag_override explanation
In designing a potential UI for a configuration of `enable_tag_override`,
I found the documentation confusing and lengthy. Here, I've made an
attempt at re-writing this section to be more concise and clear.

I also made a few small changes to the organization of this file to map
explanations to the order of the properties listing at the top. I find
it easier to scan docs when explanations appear in the same order they
are listed at the top. For explanations that span multiple paragraphs, I
provided a subheading, which also helps in linking from other pages.

Finally, I removed a duplicated paragraph from the documentation.

Ensure that errors setting up the DNS servers get propagated back to the shell (#4598)
Fixes: #4578 

Prior to this fix if there was an error binding to ports for the DNS servers the error would be swallowed by the gated log writer and never output. This fix propagates the DNS server errors back to the shell with a multierror.

Pierre Souchay eddcf228ea Implementation of Weights Data structures (#4468)
* Implementation of Weights Data structures

Adding this datastructure will allow us to resolve the
issues #1088 and #4198

This new structure defaults to values:
```
   { Passing: 1, Warning: 0 }
```

Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.

* Implemented weights for DNS SRV Records

* DNS properly support agents with weight support while server does not (backwards compatibility)

* Use Warning value of Weights of 1 by default

When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.

Thus, we put a default value of 1 to be consistent with existing behaviour.

* Added documentation for new weight field in service description

* Better documentation about weights as suggested by @banks

* Return weight = 1 for unknown Check states as suggested by @banks

* Fixed typo (of -> or) in error message as requested by @mkeeler

* Fixed unstable unit test TestRetryJoin

* Fixed unstable tests

* Fixed wrong Fatalf format in `testrpc/wait.go`

* Added notes regarding DNS SRV lookup limitations regarding number of instances

* Documentation fixes and clarification regarding SRV records with weights as requested by @banks

* Rephrase docs
