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.)

Description: This field is used to carry opaque and implementation
dependent information of the upstream endpoints. The information may
be used by management server for debugging purposes.
Example: Consider a requirement of per 'user' load stastics for
debugging. Envoy will embed user info into the metadata field for
every upstream endpoint it sends load to. This user information will
be used by management server for debugging.
Sample message:
message ClusterStats {
cluster_name = ...
message UpstreamLocalityStats {
locality = ...
message UpstreamEndpointStats {
address = "endpoint1"
metadata = { "user" : "alice"}
...
}
message UpstreamEndpointStats {
address = "endpoint1"
metadata = { "user" : "bob"}
...
}
message UpstreamEndpointStats {
address = "endpoint2"

Currently health check failure events are only log if the HealthFlag for a host transition from non-FAILED_ACTIVE_HC to FAILED_ACTIVE_HC. However, since hosts are initialized in the FAILED_ACTIVE_HC state, hosts that never became healthy have no events associated with it.
Since the current health check events only log transitions, we'll have to scan the entire log in order to find the hosts in a current failing state. Then we'll still have to filter the hosts permanently removed from the cluster by the discovery service. This makes the events very difficult to use in operations.
Proposed solution
Both of these 2 issues can be solved by emitting a health check failure event if either of these conditions are true:
If the active health check failed and it's the first health check for a host. This ensures we have events for hosts that never became healthy.
If the active health check failed and a AlwaysLogFailures configuration is set to true, by default this flag is set to false. This makes it very easy to find the hosts currently failing by looking at the last few seconds of logs.
