fix(aws): error with other instances without tags

while starting the cluster, and having already other non-kubernetes
instances active without tags, an KeyError throwed.
enhancement(aws): checks for existing kubernetes vpc first

without this check, kube-up creates a new vpc every time. Now it will
reuse the vpc tagged Kubernetes.
enhancement(aws): using iam role to pass aws credentials
enhancement(aws): added logging variable and more verbose output
fix(aws): fix with non us standard region
fix(aws): cloud provider wasn't set, corrected cloud config syntax
Specify AWS_DEFAULT_REGION to match configured region

The AWS CLI is configured with a default region, but it might not match
the configured Kubernetes region.  Specify the region to be sure.
unit test for #2815, as requested by @brendandburns
require names for gets
Actually set repository QPS in the kubelet.
Fixes malformed OBJECT_URL in rackspace setup script
Add --times to e2e.go

Make each test available for execution --times times. Acts like a
multi-deck shoe. (Otherwise this is easily scriptable outside the
e2e.go command).

Useful for "I want to walk away for a few hours leaving some end-to-ends
running", until we have more stress tests. Also useful for detecting
flakes.

Reporting is changed to break out Passed, Flaky and Failed. I chose to
keep all three lines even if --times isn't on, just for consistency in
scraping. Similarly, it always outputs the counts now. A report looks
like:

2014/12/09 07:31:21 Passed tests: goe2e.sh[100/100] guestbook.sh[100/100] private.sh[100/100] services.sh[100/100]
2014/12/09 07:31:21 Flaky tests: basic.sh[99/100] certs.sh[99/100] monitoring.sh[98/100] pd.sh[98/100] update.sh[98/100]
2014/12/09 07:31:21 Failed tests:
2014/12/09 07:31:21 8 test(s) failed.
Add Test Anything Protocol (TAP) output to e2e.go

Adds a --tap option to change outputs to match the TAP format. Changes
pass/fail in general to "ok" / "not ok".
Modifies kubectl log cmd to not require container arg for single-container pods (for #2847)
Handle PD already being attached to the machine.
Fixes the minion yaml as well
Merge pull request #2869 from brendandburns/salt

Actually set repository QPS in the kubelet.
make kubelet listen on 0.0.0.0 in the fedora guide

Listenging on the hostname is just straight up broken
Stop telling people how to launch a pod.  That's what 101 is for.
Remove a bunch of boilerplate and testing/poking as you go
