Dan Duvall e19af64fe3 http: Support additional request headers ...

Support additional request header fields for HTTP sources, "Accept" and
"User-Agent" as a start.

The "Accept" header is required in some cases and some servers may vary
the response body based on the header value.

The "User-Agent" header may be useful in custom frontends and
potentially other cases.

 - llb: Add `llb.Header` and `HTTPInfo.Header` to allow `client/llb`
   users to set these header fields on HTTP sources. The argument to
   `llb.Header` is a struct to effectively limit header fields to a
   subset.
 - llb: Define and flag new `source.http.header` capability when
   `llb.Header` is used.
 - solver: Define new `http.header.` source attribute prefix. Giving
   each header field its own attribute (opposed to JSON encoding the
   header struct) will allow source policy to make assertions on
   individual header fields.
 - source/http: Parse `http.header.` attributes into a sorted slice and
   include them in cache key digest.
 - source/http: Set request headers accordingly.
