ktest: Add MIN_CONFIG_TYPE to allow making a minum .config that has network

Add a MIN_CONFIG_TYPE that can be set to 'test' or 'boot'. The default
is 'boot' which is what make_min_config has done previously: makes a
config file that is the minimum needed to boot the target.

But when MIN_CONFIG_TYPE is set to 'test', not only must the target
boot, but it must also successfully run the TEST. This allows the
creation of a config file that is the minimum to boot and also
perform ssh to the target, or anything else a developer wants.

 #   and will not be tested again in later runs.
 #   (optional)
 #
+#  MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
+#   test if the created config can just boot the machine. If this is
+#   set to 'test', then the TEST option must be defined and the created
+#   config will not only boot the target, but also make sure that the
+#   config lets the test succeed. This is useful to make sure the final
+#   config that is generated allows network activity (ssh).
+#   (optional)

 # Example:
 #
 #  TEST_TYPE = make_min_config
 #  OUTPUT_MIN_CONFIG = /path/to/config-new-min
 #  START_MIN_CONFIG = /path/to/config-min
 #  IGNORE_CONFIG = /path/to/config-tested
+#  MIN_CONFIG_TYPE = test
+#  TEST = ssh ${USER}@${MACHINE} echo hi
