Update gophercloud dependency to v1.0.0
Update openstack provider to gophercloud v1.0 API
Implement TCPLoadBalancer OpenStack cloud provider

Also add a trivial implementation of Zones() too.

This only supports a single region/zone currently (the region where
kubernetes is running).
Add additional logging to openstack cloud provider

Turned out to be invaluable while debugging issues - I expect it will be
for others too.

Conflicts:

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.

Updated types API to include session affinity. …

Track the sources that the kubelet has seen, and only delete pods
when every source has been seen at least once.
