The specification for cookie-based stateful session affinity
where the date plane supplies a “session cookie” with the name
"GSSA" which encodes a specific destination host and each
request containing that cookie will be directed to that host as
long as the destination host remains up and healthy.
The gRPC proxyless mesh library or sidecar proxy will manage the
session cookie but the client application code is responsible
for copying the cookie from each RPC in the session to the next.
