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.

Fix various test failures and vet warnings.
Intention de-duplication in previously merged PR actualy failed some tests that were not caught be me or CI. I ran the test files for state changes but they happened not to trigger this case so I made sure they did first and then fixed. That fixed some upstream intention endpoint tests that I'd not run as part of testing the previous fix.

Yoann Fouquet f4f7db0059 [Fix] Service tags not added to health checks
Since commit 9685bdcd0ba4b4b3adb04f9c1dd67d637ca7894e, service tags are added to the health checks.
Otherwise, when adding a service, tags are not added to its check.

In updateSyncState, we compare the checks of the local agent with the checks of the catalog.
It appears that the service tags are different (missing in one case), and so the check is synchronized.
That increase the ModifyIndex periodically when nothing changes.

Fixed it by adding serviceTags to the check.

Note that the issue appeared in version 0.8.2.
Looks related to #3259.

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.

Frank Schroeder 62c77d70f0 build: make tests independent of build tags
When the metadata server is scanning the agents for potential servers
it is parsing the version number which the agent provided when it
joined. This version number has to conform to a certain format, i.e.
'n.n.n'. Without this version number properly set some tests fail with
error messages that disguise the root cause.

The default version number is currently set to 'unknown' in
version/version.go which does not parse and triggers the tests to fail.
The work around is to use a build tag 'consul' which will use the
version number set in version_base.go instead which has the correct
format and is set to the current release version.

In addition, some parts of the code also require the version number to
be of a certain value. Setting it to '0.0.0' for example makes some
tests pass and others fail since they don't pass the semantic check.

When using go build/install/test one has to remember to use '-tags
consul' or tests will fail with non-obvious error messages.

Using build tags makes the build process more complex and error prone
since it prevents the use of the plain go toolchain and - at least in
its current form - introduces subtle build and test issues. We should
try to eliminate build tags for anything else but platform specific
code.

This patch removes all references to specific version numbers in the
code and tests and sets the default version to '9.9.9' which is
syntactically correct and passes the semantic check. This solves the
issue of running go build/install/test without tags for the OSS build.

James Phillips 8572931afe Cleans up version 8 ACLs in the agent and the docs. (#3248)
* Moves magic check and service constants into shared structs package.

* Removes the "consul" service from local state.

Since this service is added by the leader, it doesn't really make sense to
also keep it in local state (which requires special ACLs to configure), and
requires a bunch of special cases in the local state logic. This requires
fewer special cases and makes ACL bootstrapping cleaner.

* Makes coordinate update ACL log message a warning, similar to other AE warnings.

* Adds much more detailed examples for bootstrapping ACLs.

This can hopefully replace https://gist.github.com/slackpad/d89ce0e1cc0802c3c4f2d84932fa3234.

Frank Schroeder 0ed76615d3 rpc: monkey patch fix for data races for localState
The tests that use the localState of the agent access the internal
variables and call methods which are not guarded by locks creating
data races in tests. While the use of internal variables is somewhat
easy to spot the fact that not all methods are thread-safe is a
surprise.

A proper fix requires the localState struct to be moved into its own
package so that tests in the agent can only access the external
interface.

However, the localState is currently dependent on the agent.Config
which would create a circular dependency. Therefore, the Config
struct needs to be moved first for this to happen.

This patch literally monkey patches the use of the lock around the
cases which have data races and marks them with a
// todo(fs): data race comment.
