implementing the first roadmap steps in #11264, i.e. some simple delta discovery flows with core

Currently, the header-to-metadata filter supports adding
a header's value to a metadata key. This extends this to
support performing a regex match & substitution before
the value is added as metadata.
The use-case we have is extracting parts of a the :path
header and using those as metadata for routing decisions
via the subset LB.

This PR proposes to rename the RetryPolicy field num_retries to max_retries.
This parameter exists in two places: 1) the RetryPolicy message in the route configuration and 2) the header x-envoy-max-retries. The naming inconsistency is a UX papercut. max_retries feels like right name for what this field is for ie. the maximum number of retries that are permitted.
There is also a stripped down RetryPolicy message which is used by RemoteDataSource which has a num_retries field. I'm including a matching rename of that for consistency.

This adds the option allow_insecure_cluster_options to the dynamic forward proxy's cluster configuration.
Enabling this flag allows disabling auto_sni and auto_san_validation in the cluster's UpstreamHttpProtocolOptions, which was previously disallowed.
This allows use where e.g. automatic adding of an exact SAN matcher for the original authority is undesirable, while preserving the existing "safe
by default" behaviour for most use cases.

Notice that identifier is defined in api/envoy/config/core/v3/protocol.proto as:
google.protobuf.UInt32Value identifier = 1
[ (validate.rules).uint32 = {lte: 65536 gte: 1}, (validate.rules).message = {required: true} ];
The value should range from 0 to 65535 instead of from 1 to 65536.
Because 65536 is greater than uint16::max, it triggers the assert to terminate the program.
The fix is to set it to {lte:65535 gte:0}, instead of {lte: 65536 gte: 1}
