8d3011fb9c etcd: Add a timeout for etcd server to start correctly 
This also updates etcd to a newer version with a fix that allows this
detection and timeout operation to be possible.

9260066fa3 tests: Workaround regression in two host etcd clusters 
If you don't give your two host cluster enough time to "feel healthy",
it will generate an error if you do operations within five seconds. This
is a regression and the five seconds is also quite arbitrary. This is
detailed at: https://github.com/coreos/etcd/issues/6305

This seems to be a bit of a race condition, even with a 10s timer, so
this also disables the StrictReconfigCheck. Re-enable this as soon as
possible.

db4de12767 Add more flexibility around the prefixes available 
This allows you to specify a custom prefix, or a tmp prefix which is
chosen automatically.

d429795737 Improve the configWatcher array to allow N files

276219a691 Run tests with a tmp prefix 
This will avoid failures if /var/lib/mgmt/ isn't writable.

03c1df98f4 Improve prefix creation and feedback 
This makes the default /var/lib/mgmt/ directory, but also allows you to
use a prefix in /tmp/ automatically if you can't write anywhere else.

ad1e48aa2d Add caching for remote execution 
This speeds up copying of the binary for slow connections. It also
finally adds a universal directory prefix for mgmt!

7032eea045 Remote "agent-less" mode 
This is a new mode to be used for bootstrapping mgmt clusters or in
situations with tight operational restrictions.

This includes the basics, additional functionality will follow!

4ca98b5f17 Allow make overrides of version if git fails 
If the $(shell ...) command fails, the ':=' operator fails as well
preventing variable overrides from functioning.

Wrap the assignment in an $(or ...) to prevent the shell script from
running if the variable is set from the command line or the environment.

Fixes issue #58

4e00c78410 Change "uname -i" to "uname -m" to be portable 
According to the documentation for uname:

       -m, --machine
              print the machine hardware name

       -i, --hardware-platform
              print the hardware platform (non-portable)

So use the portable -m version.

24ba6abc6b Don't block on member exits 
The MemberList() function which apparently looks at all of the endpoints
was blocking right after a member exited, because we still had a stale
list of endpoints, and while a member that exited safely would update
the endpoints lists, the other member would (unavoidably) race to get
that message, and so it might call the MemberList() with the now stale
endpoint list. This way we invalidate an endpoint we know to be gone
immediately.

This also adds a simple test case to catch this scenario.

f6c1bba3b6 Avoid a rare panic if DestroyServer is called early

examining the WaitGroup code that gets .Done() by DestroyServer().

have all the resources to do so right now. If you want to help, please
let me know!
