BUILD: http: include types/sample.h in proto_http.h
Commit d7c9196 ("MAJOR: filters: Add filters support") removed sample.h
from proto_http.h, but it has become necessary as of commit fd7edd3
("MINOR: Move http method enum from proto_http to sample") in order
to have HTTP_METH_*. Due to this, the "debug/flags" utility doesn't
build anymore.
