super1: remove support for name= in config

super1: remove support for name= in config

Only super1 provides "name=" to config. It is recoreded in metadata
so there is no need to duplicate same information.
UUID is our main key.

It is not used by Incremental and Assemble handles empty name well
because other supertypes don't set it in conf.

Expectation that the name in config is same as in metadata is bug prone.
Config should be the place where use can define customized settings.

Remove printing "name=" from mdadm config creation commands. Ignore
the name in config file to keep backward compatibility. Remove
description from man mdadm.conf.

Update 00conftest because "name" is no longer accepted.
As the name is ignored, error for mdadm --detail is not printed.
