total_issued_requests field tracks the count of requests issued since
the last report. This field will be used for global load balancing
decisions.
Envoy maintains a stats counter rq_total to track total
requests made. By latching this counter when load reporting period
begins, we are able to count the total requests issued in a load
reporting interval. This information is then used to populate the field
total_issued_requests.
Risk Level: Low
Testing: //test/integration:load_stats_reporter passes.

This adds support for modifying the grpc-timeout provided by the
downstream by some offset. This is useful to make sure that Envoy is
able to see timeouts before the gRPC client does, as the client will
cancel the request when the deadline has been exceeded which hides the
timeout from the outlier detector.

We use the default subset as our fallback policy. However, if there's
a problem with our metadata it's possible for the default subset
to become empty. In this case, we'd like any host to be selected.
This change adds a panic_mode_any boolean option to LbSubsetConfig
to enable this behavior.

Adds a DEGRADED HealthStatus value that can be set on a host through
LoadAssignment, allowing for a host to be marked degraded without
the need for active health checking.
Moves the mapping of EDS flag to health flag to inside
`registerHostForPriority`, which means that we're now consistently setting
the EDS health flag for EDS/STATIC/STRICT_DNS/LOGICAL_DNS.
Simplifies the check for whether the health flag value of a host has
changed during EDS updates.
Adds tests for the EDS mapping as well as tests to verify that we're
honoring the EDS flag for non-EDS cluster types.
Risk Level: High, substantial refactoring of how we determine whether health flag has changed.
Testing: UTs coverage for new health flag values.

Allows both upstream-driven and filter-controlled internal redirects, basically rerunning the whole filter chain for a new stream.
The current implementation is limited to requests-sans-bodies and complete-requests, and num-redirects = 1, but could be fairly easily extended (probably in a follow-up) to remove any of these restrictions.
I do need to add more unit tests here, but I want to make sure we're happy both the validation we're doing and where we do it. For example while this implementation forces N=1 for upstream internal redirects it allows filters to impose their own separate limits and allows them to screw up w.r.t. redirect loops. We could globally enforce by disallowing recreateStream if is_internally_created_ true but I could imagine wanting different limits for a filter redirect than an external redirect so am mildly inclined to allow filters to enforce on their own with internal checks as the router filter does.
TODO(alyssawilk) in a follow-up before killing off the initial stream, pass it the original StreamInfo and copy relevant fields (downstream timing info etc.)
