REGTESTS: ssl: Add "new/del ssl ca-file" tests

This vtc tests the "new ssl ca-file" which allows to create a new empty
CA file that can then be set through a "set+commit ssl ca-file" command
pair. It also tests the "del ssl ca-file" command which allows to delete
an unused CA file.

+# This test uses the "new ssl ca-file" and "del ssl ca-file" commands to create
+# a new CA file or delete an unused CA file.
+#
+# It requires socat to upload the CA file.
+#
+# If this test does not work anymore:
+# - Check that you have socat
