Pierre Souchay 473e589d86 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

config: return error on extra command line arguments (#3397)
The `consul agent` command was ignoring extra command line arguments
which can lead to confusion when the user has for example forgotten to
add a dash in front of an argument or is not using an `=` when setting
boolean flags to `true`. `-bootstrap true` is not the same as
`-bootstrap=true`, for example.

Since all command line flags are known and we don't expect unparsed
arguments we can return an error. However, this may make it slightly
more difficult in the future if we ever wanted to have these kinds of
arguments.

Fixes #3397

the next port is chosen. So far it seems rare enough to live
with it.

agent: support custom check id and name
This patch adds support for a custom check id and name when
registering a service.

This is achieved by adding a CheckID and a Name field to the
CheckType structure which is used to register checks with a
service and when returning health check definitions.

CheckDefinition is a superset of CheckType which duplicates
some of the fields of CheckType. This patch decouples these
two structures by removing the embedding of CheckType in
CheckDefinition.

Frank Schroeder d6eb1d434f agent: Replace client/server with delegate interface
This patch adds a new internal interface clientServer
which defines the common methods of consul.Client and
consul.Server. This allows to replace the following
code

    if a.server != nil {
        a.server.do()
    } else {
        a.client.do()
    }

with

    a.delegate.do()

In case a specific type is required a type check can
be performed:

    if srv, ok := a.delegate.(*consul.Server); ok {
        srv.doSrv()
    }

Frank Schroeder eedf0f3ac5 test: add helper for ioutil.TempDir/TempFile
This creates a simplified helper for temporary directories and files.
All path names are prefixed with the name of the current test.
All files and directories are stored either in /tmp/consul-test
or /tmp if the former could not be created.

Using the system temp dir breaks some tests on macOS where the unix
socket path becomes too long.

Frank Schroeder 9f8f258d4d Remove duplicate constants
This patch removes duplicate internal copies of constants in the structs
package which are also defined in the api package. The api.KVOp type
with all its values for the TXN endpoint and the api.HealthXXX constants
are now used throughout the codebase.

This resulted in some circular dependencies in the testutil package
which have been resolved by copying code and constants and moving the
WaitForLeader function into a separate testrpc package.

Cleans up a stray mark and fixes unit tests.
Ended up removing the leader_test.go server address change test as part
of this. The join was failing becase we were using a new node name with
the new logic here, but realized this was hitting some of the memberlist
conflict logic and not working as we expected. We need some additional
work to fully support address changes, so removed the test for now.

Removes remoteConsuls in favor of the new router.
This has the next wave of RTT integration with the router and also
factors some common RTT-related helpers out to lib. While we were
in here we also got rid of the coordinate disable config so we don't
need to deal with the complexity in the router (there was never a
user-visible way to disable coordinates).
