First off, sorry for the noise. This is a cleaner step of #8508
Found more of a root cause of the open file handles.
After more testing I found that the open file descriptors will still
occur for TCP:// connections to the daemon, causing client and/or daemon
to fail.
The issue was instantiating a new http.Transport on _ever_ client
request. So each instance held the prior connection alive, but was only
ever used once.
By moving it out to the initilization of DockerCli, we can now have
reuse of idled connections. Simplifies the garbage overhead of the
client too, though that's not usually a deal.

In the go stdlib net/http Transport, the used connections are cached
when idled. This behaviour is intended for TCP connections and does not
behave correctly for unix sockets. Despite the
DefaultMaxIdleConnsPerHost being 2, the idled connections are held open
during a session. For large sessions like `docker rm $(docker ps -a -q)`
of thousands of containers, it will cause the client _and_ the server to
open too many fails and have failures.
Having keep alives not used for only unix sockets is a work around for
this stdlib issue.
Also this includes disabling compression when communicating over the
local unix socket too.

Fixes#8407
Setting Host on URL only works if the Request does not
already have its Host property set.
Note that the API version was also swallowed.
