The documentation for these options has been incorrect ever since their
addition via commit 084dcb55. This broke upgrading a CoreOS stable
cluster to 410.0.0 because the user was using the example TOML config
which contains:
http_write_timeout = 10
This was silently ignored in the old stable version which predates the
addition of these options. After upgrading etcd began failing with:
Type mismatch for 'config.Config.http_write_timeout': Expected float
but found 'int64’.
Original issue: https://github.com/coreos/update_engine/issues/45
The default is for connections to last forever[1]. This leads to fds
leaking. I set the timeout so high by default so that watches don't have
to keep retrying but perhaps we should set it slower.
Tested on a cluster with lots of clients and it seems to have relieved
the problem.

This is an initial version of the bootstrap code that seems to work
under the normal circumstances. I need to mock out a server that will
test out all of the error cases now.
