Bumped up compat for HTTP.jl

[svilupp]

Would it be possible to increase the compat for HTTP.jl to 1.2?
I've re-run the testing suite and all passes

Motivation:
MLFlow-based workflows are more likely to have connection timeouts, which leads to a lot of HTTP.jl errors like IOError(EOFError()) (eg, JuliaWeb/HTTP.jl#233)

There have been a lot of fixes in HTTP.lj since version 0.9 (see JuliaWeb/HTTP.jl#903), so we would be able to benefit from that.
