Dave Walker (Daviey) 4958154640 Enable kernel.version on Windows
Previously, this value was guarded against running on Windows
because it called the `uname` command which is unlikely to
be there.

This change now sets the value from gopsutil, which might
well be an empty string.

Dave Walker (Daviey) 090e760928 Don't exec uname for node attribute kernel.version
Previously with client fingerprinting, sys/exec's Command
function was being used to execute `uname -r` and the return
string processed into the kernel.version node attribute.

This change uses gopsutil/host KernelVersion function
instead.  This means we can drop the os/exec, strings and
fmt imports... and not execute an external binary.

Alex Dadgar 9497991590 Updated AWS speeds and network_speed now overrides
This PR:

* Makes AWS network speeds more granular
* Makes `network_speed` an override and not a default
* Adds a default of 1000 MBits if no network link speed is detected.

Fixes #1985

Remove cgroup fingerprinter from non-linux systems.
If someone wants to extend or reuse Cgroup detenction in the future they
can move `cgroup_linux.go` to `cgroup.go` and add the relevant build
tags.

Skip the network fingerprinter test when offline.
Conditionalize the network fingerprinter test so that it works when a
user is offline.  Similarly, when the network fingerprint test fails in
the future pass a HINT to the user to set an env var to allow the test
to be skipped in the future.

Build the Cgroup fingerprinter on only Linux.
Change the logic from `!linux` to an empty build tag so that *if*
another platform picks up Cgroups support they can add themselves to the
necessary build tags for this fingerprinter and be on their way.
Because this technology isn't inherently Linux-specific and isn't
mutually exclusive of other resource isolation containers, resist the
urge to rename the Cgroup fingerprinter to something generic like the
ResourceContainerFingerprinter.

Provide a default ConsulConfig for client/config.DefaultConfig()
Change the unit test to only test if the consul link exists, not the
value of the link.  The old test was hostname specific and therefore
would always be different based on the environment running the tests.

Reconcile, clean up, and centralize API version numbers (major and minor).
Reduce future confusion by introducing a minor version that is gossiped out
via the `mvn` Serf tag (Minor Version Number, `vsn` is already being used for
to communicate `Major Version Number`).

Guillaume Jacquet 4a3e709eef Fix AWS metadata url
Fix URL. It was printing an error message on startup:
```
2015/11/13 15:49:21 [ERR] fingerprint.env_aws: Error querying AWS Metadata URL, skipping
```

By the way is it safe to use latest? Is there a chance that Amazon decides to change the format of the metadata? It could be safer to use something like `http://169.254.169.254/2014-11-05/meta-data`
