ConfigurableParameter: do not magically overwrite the 'name' attribute

The ClassVarMeta metaclass used to derive each ConfigurableParameter's
'name' attribute automatically from the Python class name (via
camel_to_snake()).  Stop doing this, for three reasons:

1) Python class names follow constraints that do not fit the naming
   commonly used in CSV files.  For example, a name like
   "5GS-SUCI-CalcInfo" starts with a digit and contains dashes,
   neither of which is permissible in a class name.

2) Python class names live in their own namespace, distinct from the
   one used to present eSIM parameters to end users.  Deriving the UI
   name from the class name couples these two namespaces together.

   Taken together, (1) and (2) mean that automatic naming both imposes
   class-name constraints on the user-visible names and merges the
   internal Python namespace with the publicly shown one - a layer
   violation from the perspective of UI design.

3) Overriding 'name' from __new__() makes manual naming impossible: a
   subclass that sets 'name = "bar"' as a class attribute would still
   end up with the value computed by the metaclass, which is
   surprising and hard to track down:

       class MySuper(metaclass=...):  # __new__ sets name = 'foo'
           ...
       class MySub(MySuper):
           name = 'bar'
       print(MySub().name)  # 'foo', not 'bar' as one would expect
