Adds a feature flag to enable HTTP (non-TLS) for the events etcd
cluster. This matches what GCE scale tests do and helps avoid TLS
handshake overhead for ephemeral events data.

Main etcd always uses HTTPS - no way to disable TLS there.

Usage: export KOPS_FEATURE_FLAGS=EtcdEventsHTTP

Enable the EtcdEventsHTTP feature flag in scalability tests to use
HTTP for the events etcd cluster, reducing TLS handshake overhead.

This matches what GCE scale tests do and helps avoid connection
proliferation issues at scale.

This helps diagnose issues where feature flags may not be recognized,
such as build caching problems or initialization ordering issues.

The sflags library splits comma-separated values in --env flag arguments
into separate slice elements. This breaks KOPS_FEATURE_FLAGS values like
"EtcdEventsHTTP,AWSSingleNodesInstanceGroup" because they get split into
separate entries in the Env slice.

Fix by reassembling the original value: collect all entries starting from
KOPS_FEATURE_FLAGS= until we hit another NAME=VALUE pattern, then join
them back together with commas.
