agent/config: add managed proxy upstreams config to skip
agent/config will turn [{}] into {} (single element maps into a single
map) to work around HCL issues. These are resolved in HCL2 which I'm
sure Consul will switch to eventually.

This breaks the connect proxy configuration in service definition FILES
since we call this patch function. For now, let's just special-case skip
this. In the future we maybe Consul will adopt HCL2 and fix it, or we
can do something else if we want. This works and is tested.

agent: change connect command paths to be slices, not strings
This matches other executable configuration and allows us to cleanly
separate executable from arguments without trying to emulate shell
parsing.

Pierre Souchay 09970479b5 Allow to control the number of A/AAAA Record returned by DNS
This allows to have randomized resource records (i.e. each
answer contains only one IP, but the IP changes every request) for
A, AAAA records.

It will fix https://github.com/hashicorp/consul/issues/3355 and
https://github.com/hashicorp/consul/issues/3937

See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509
for details.

It basically add a new option called `a_record_limit` and will not
return more than a_record_limit when performing A, AAAA or ANY DNS
requests.

The existing `udp_answer_limit` option is still working but should
be considered as deprecated since it works only with DNS clients
not supporting EDNS.

Frank Schröder 3cb1cd3723 config: add -config-format option (#3626)
* config: refactor ReadPath(s) methods without side-effects

Return the sources instead of modifying the state.

* config: clean data dir before every test

* config: add tests for config-file and config-dir

* config: add -config-format option

Starting with Consul 1.0 all config files must have a '.json' or '.hcl'
extension to make it unambigous how the data should be parsed. Some
automation tools generate temporary files by appending a random string
to the generated file which obfuscates the extension and prevents the
file type detection.

This patch adds a -config-format option which can be used to override
the auto-detection behavior by forcing all config files or all files
within a config directory independent of their extension to be
interpreted as of this format.

Fixes #3620

Frank Schröder 9b2e3c2091 agent: add option to discard health output (#3562)
* agent: add option to discard health output

In high volatile environments consul will have checks with "noisy"
output which changes every time even though the status does not change.
Since the output is stored in the raft log every health check update
unblocks a blocking call on health checks since the raft index has
changed even though the status of the health checks may not have changed
at all. By discarding the output of the health checks the users can
choose a different tradeoff. Less visibility on why a check failed in
exchange for a reduced change rate on the raft log.

* agent: discard output also when adding a check

* agent: add test for discard check output

* agent: update docs

* go vet

* Adds discard_check_output to reloadable config table.

* Updates the change log.

Frank Schröder fa22ad4573 config: add generic method to translate between CamelCase and snake_case (#3557)
* doc: document discrepancy between id and CheckID

* doc: document enable_tag_override change

* config: add TranslateKeys helper

TranslateKeys makes it easier to map between different representations
of internal structures. It allows to recursively map alias keys to
canonical keys in structured maps.

* config: use TranslateKeys for config file

This also adds support for 'enabletagoverride' and removes
the need for a separate CheckID alias field.

* config: remove dead code

* agent: use TranslateKeys for FixupCheckType

* agent: translate enable_tag_override during service registration

* doc: add '.hcl' as valid extension

* config: map ScriptArgs to args

* config: add comment for TranslateKeys

James Phillips d1ad538345 Makes RPC handling more robust when rolling servers. (#3561)
* Adds client-side retry for no leader errors.

This paves over the case where the client was connected to the leader
when it loses leadership.

* Adds a configurable server RPC drain time and a fail-fast path for RPCs.

When a server leaves it gets removed from the Raft configuration, so it will
never know who the new leader server ends up being. Without this we'd be
doomed to wait out the RPC hold timeout and then fail. This makes things fail
a little quicker while a sever is draining, and since we added a client retry
AND since the server doing this has already shut down and left the Serf LAN,
clients should retry against some other server.

* Makes the RPC hold timeout configurable.

* Reorders struct members.

* Sets the RPC hold timeout default for test servers.

* Bumps the leave drain time up to 5 seconds.

* Robustifies retries with a simpler client-side RPC hold.

* Reverts untended delete.

Frank Schröder 707f8e329a Metrics service prefix (#3498)
* metrics: replace statsite_prefix with service_prefix

The metrics prefix isn't statsite specific and is in fact used
for all metrics providers. Since we are deprecating fields
anyway we should fix this one as well.

Fixes #3293

* Updates docs and sorts telemetry section.

* Renames to "metrics_prefix" to disambiguate with Consul services.

* Updates the change log.

Frank Schröder 69a088ca85 New config parser, HCL support, multiple bind addrs (#3480)
* new config parser for agent

This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:

 * add HCL support
 * all configuration fragments in tests and for default config are
   expressed as HCL fragments
 * HCL fragments can be provided on the command line so that they
   can eventually replace the command line flags.
 * HCL/JSON fragments are parsed into a temporary Config structure
   which can be merged using reflection (all values are pointers).
   The existing merge logic of overwrite for values and append
   for slices has been preserved.
 * A single builder process generates a typed runtime configuration
   for the agent.

The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.

The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.
