James Bardin fea32fb7d7 retry locks on network errors (#3553)
* retry locks on network errors

When communicating with a local agent and watching a lock, a dropped
connection between the agent and server will show up as a server error
and immediately be retried. However if the client is connected to a
remote server, a dropped connection immediately aborts the lock.

* Updates comment about it being unsafe for writes.

Frank Schröder 12216583a1 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.

* use base command arg parsing to format help output properly

* handle -dc deprecation case in Build

* switch autopilot.max_trailing_logs to int

* remove duplicate test case

* remove unused methods

Illirgway e0cc1ce679 Fix bug with unused (replaced with "") CONSUL_HTTP_AUTH in some places
example: https://github.com/hashicorp/consul/blob/master/watch/plan.go#L26

	conf := consulapi.DefaultConfig()
	conf.Address = address
	conf.Datacenter = p.Datacenter
	conf.Token = p.Token                             # <-- replace Token from DefaultConfig/CONSUL_HTTP_AUTH with ""
	client, err := consulapi.NewClient(conf)

how to reproduce bug:
0. consul -> localhost:8500 with more than 0 service checks
1. deny all for anonymous token
2. create appropriate acl <token> for watch checks (agent:read + node:read,service:read)
3. bash:
CONSUL_HTTP_AUTH=<token> consul watch -http-addr=localhost:8500 -type=checks # --> return []
consul watch -http-addr=localhost:8500 -type=checks -token=<token> # -> return { .... right json result .... }

Two of the changes are in tests; the one of consequence is in the API.
As explained in #1308 this can cause conflicts with downstream programs.

Fixes #1308.

Jeff Mitchell 11a3ce0bdd RPC and HTTP interfaces fully generically-sockified so Unix is supported.
Client works for RPC; will honor CONSUL_RPC_ADDR. HTTP works via consul/api;
honors CONSUL_HTTP_ADDR.

The format of a Unix socket in configuration data is:
"unix://[/path/to/socket];[username or uid];[gid];[mode]"

Obviously, the user must have appropriate permissions to create the socket
file in the given path and assign the requested uid/gid. Also note that Go does
not support gid lookups from group name, so gid must be numeric. See
https://codereview.appspot.com/101310044

When connecting from the client, the format is just the first part of the
above line:
"unix://[/path/to/socket]"
