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.
This enables `consul agent -dev` to begin using Connect features with
the built-in CA. I think this is expected behavior since you can imagine
that new users would want to try.
There is no real downside since we're just using the built-in CA.
There are also a lot of small bug fixes found when testing lots of things end-to-end for the first time and some cleanup now it's integrated with real CA code.

* 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
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
DNS recursors can be added through go-sockaddr templates. Entries
are deduplicated while the order is maintained.
