Sometimes need to limit the receive speed of git `clone/fetch`
because of the limited network bandwidth, otherwise will prevent
other applications from using the network normally.
Add `http.maxReceiveSpeed` to limit `git-receive-pack` receiving
speed, Can be overridden by `GIT_HTTP_MAX_RECEIVE_SPEED` eivironment
variable.
The default is unlimited, same if the value is 0 or negative. The
default unit is Bytes/s, common unit suffixes of k, m, or g are supported.
this configuration is valid for `clone`, `fetch`, `pull` commands of the
https protocol, and only supports libcurl 7.15.5 and above.
