Docker/Openshift/Kubernetes mount the config file as a symbolic link and
IsDir returns true if the file is a symlink. Before calling IsDir, the
symlink should be resolved to determine if it points at a file or
directory.
Fixes#3753
* 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.

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

* 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.
* 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
