Make etcd cache size configurable
Instead of the prior 50K limit, allow users to specify a more sensible size for their cluster.
I'm not sure what a sensible default is here. I'm still experimenting on my own clusters. 50 gives me a 270MB max footprint. 50K caused my apiserver to run out of memory as it exceeded >2GB. I believe that number is far too large for most people's use cases.
There are some other fundamental issues that I'm not addressing here:
- Old etcd items are cached and potentially never removed (it stores using modifiedIndex, and doesn't remove the old object when it gets updated)
- Cache isn't LRU, so there's no guarantee the cache remains hot. This makes its performance difficult to predict. More of an issue with a smaller cache size.
- 1.2 etcd entries seem to have a larger memory footprint (I never had an issue in 1.1, even though this cache existed there). I suspect that's due to image lists on the node status.
This is provided as a fix for #23323

hack: specify --advertise-address in hack/local-up-cluster.sh
This fixes the bug where the script fails to launch an apiserver on a
machine without active networking (issue #24272).

Fix spacing in usage_from_stdin and info_from_stdin (issue #24186).
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.

Rename "gcloud-update" jobs to "daily-maintenace" and add Docker cleanup
I'm guessing Jenkins Job Builder won't delete the old job, and we'll need to do that manually?

phase 2 of cassandra example overhaul
Here's the next iteration in overhauling this example, towards https://github.com/kubernetes/kubernetes/issues/20961. This removes the pod adoption part, but doesn't (yet) otherwise change any of the resources used.
It also includes some README cleanup, and removes some explicit specification of labels in the rc yaml.
This PR doesn't yet add any commentary on how we're using the seed provider (re: https://github.com/kubernetes/kubernetes/issues/20961#issuecomment-190405959 etc.). Maybe we should add that.
Also: LMK if this PR should include any changes to the links out to the docs.

Restart job 5m after the previous failure.
If a job flakes at the beginning of it scripts, it will likely sit around doing nothing for 30m blocking the merge queue. Decreasing this to 5m.
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line

Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.
This makes it easier to determine which tests cause particular suites to
fail.
