server_fn depedency on gloo_net 0.5 causing duplicate inclusion of http library with different versions.

[DylanRJohnston]

Hey all, this isn't exactly a bug, but I was trying to reduce the number of duplicate packages in my project with different versions in an attempt to cut down on build times and binary sizes. I've noticed that server_fns depends on gloo_net v0.5, which in turn depends on http v0.2 when the rest of the ecosystem has moved onto http v1. We should bump gloo_net to a more recent version eg. 0.9 to help reduce the inclusion of http v0.2.
