plumbing: transport/http, refactor transport to cache underlying transport objects

Refactor the in-built http transport to cache the underlying http
transport objects mapped to its specific options for each Git transport
object. This lets us reuse the transport for a specific set of configurations
as recommended. (ref: https://pkg.go.dev/net/http#Transport)
If there are no transport specific options provided, the default
transport is used.
