The ServerCacheReplayer replays captured communication with the autofill
server. With the switch of the legacy autofill server to the new API
server we want to keep using the traces recorded with the old server.

This CL extends the ServerCacheReplayer to intercept traffic to the old
and the new server, to read recorded traffice to the old and the new
server, and performs the conversion as necessary.

The ServerCacheReplayer is parameterized with a server type that is set
according to the features::kAutofillUseApi feature. If the feature is
configured to use the API server, the ServerCacheReplayer will re-encode
all stored network traffic to follow the new API server's format when
loading the data from disk. Analog steps are taken if the
ServerCacheReplayer is configured to serve as a legacy server.
