Replace code in mutation_utils.cc with code that calls into the new
mutation_rules library. Add the ability to keep a counter of failed
header mutations, and also add the ability for an invalid mutation
to cause the HTTP request to fail.

This protobuf will be used initialy by the ext_proc filter to control
which headers may be changed by an external processing server.
This begins to address #14789 .
If the proto and the location are OK, I'll go on to add a common library to test a proposed header mutation against these rules and then incorporate them into the ext_proc filter.
The eventual result is that, by default, an external processor for ext_proc will be able to modify any header, but there will be controls that an administrator can use when connecting to a processor to control whether that processor is actually allowed to make all possible changes.
Risk Level: Low -- just the proto for now
