new 2ca95ee0b Demote JDK transport (#1599)
2ca95ee0b is described below

Demote JDK transport (#1599)
Originally we have this order of transports w/ priorities (present/absent
in maven core):
* wagon -1.0 (present)
* apache 5.0 (present)
* jdk 10.0 (present) ("default" transport)
* jetty 15.0 (absent) (if user added it via extension or lib/ext it "wins")
But lately we see that JDK one advantage of HTTP/2 support (that is already
disabled due various issues) is shaded due several disadvantages (no support
for HTTPS proxies, unstable, and unreliable)
Hence, I propose to "demote" it (maybe even remove it from Maven core):
* wagon -1.0 (present)
* jdk 5.0 (present; and maybe remove it from maven core)
* apache 10.0 (present; new "default" transport)
* jetty 15.0 (absent)
This makes Maven 4 not have "modern" HTTP transport by default, but apache
transport is well battle tested and robust, with one issue: lack of HTTP/2
support (that does improve download speeds).
If we decide for this, it will have impact on Maven ITs as well that asser
default transport.
