HBASE-26903 Bump httpclient from 4.5.3 to 4.5.13 (#4296)

Bump httpclient from 4.5.3 to 4.5.13 to avoid a CVE of medium severity in this
dependency.

Newer httpclient versions enable a URI normalization algorithm by default that
rewrites URIs in a way that breaks some forms of valid REST gateway interactions,
so disable it when building the httpclient instance in Client.
