This adds an option to allow hosts to be excluded in lb calculations until they have been health checked
for the first time. This will make it possible to scale up the number of hosts quickly (ie large increase
relative to current host set size) without triggering panic mode/spillover (as long as the initial health check
is succeeds).
While these hosts are excluded from the lb calculations, they are still eligible for routing when panic
mode is triggered.

When using active health checking, hosts are not removed from
dynamic clusters if they are still passing health checks. This
creates a situation in which hosts might not be removed for a
very long time if the sequence is reversed; removal followed by
health check failure. This change handles the second case so that
any time a host is both removed AND failing active health check,
in any order, it will be removed.
This has been an issue "forever" but is more obvious when using
streaming EDS or very long polling DNS.

This allows a host to be marked as degraded by having x-envoy-degraded
returned from the HTTP active health checking response.

This adds the host's weight to the `/clusters?format=json` response.

Currently host level stats in clusters proto uses map so they are outputted in random order. This PR changes it to list so that the order is predictable.
