Motivation: `HostHeaderHttpRequesterFilter` adds a `Host` header only for HTTP/1.1. It leads to unnecessary parsing of request-target in `H2ToStH1ClientDuplexHandler.write` as an attempt to fill `:authority` pseudo-header and results in missing `:authority` pseudo-header required by gRPC protocol. Modifications: - Do not add `Host` header only for HTTP/1.0 in `HostHeaderHttpRequesterFilter`; Result: gRPC request has `:authority` pseudo-header.
