HTTP.get eats keyword arguments

[ericphanson]

On HTTP.jl v1.10.1,

julia> HTTP.get("http://localhost:31337"; nonsense=1)
ERROR: HTTP.ConnectError for url = `http://localhost:31337`: IOError: connect: connection refused (ECONNREFUSED)
Stacktrace:
 [1] getconnection(::Type{…}, host::SubString{…}, port::SubString{…}; keepalive::Bool, readtimeout::Int64, kw::@Kwargs{…})

This should be a MethodError or similiar, like

julia> f(x) = 1
f (generic function with 1 method)

julia> f(1; nonsense="abc")
ERROR: MethodError: no method matching f(::Int64; nonsense::String)

Closest candidates are:
  f(::Any) got unsupported keyword argument "nonsense"
   @ Main REPL[12]:1

This issue makes it really hard to figure out when you're using the wrong keyword argument, e.g. JuliaCloud/AWS.jl#666 (comment).

Duplicate of (the admittedly too minimal) #1024. I have some thoughts on this, but it's made tricky because of the @client macro ability for external layers to be added that may want to allow passing their own keyword arguments.
