cgtsclient handle certificate related options properly

Currently cgtsclient ignores "-k/--insecure", "--ca-file",
"--cert-file" and ""--key-file" options. In order for command
such as "system host-list" to work over HTTPS, OS_CACERT env
variable has to be set.

This change updated cgtsclient to accept and properly handle
the ignored options.

Test Plan:
PASS: remote cli docker image build
PASS: from remote cli environment, successfully run the
      "system host-list" commands with the 4 options over
      HTTPS.
