Modules generated by the module creation machinery currently print out
a notice that warnts the user that things are being autoloaded. In
some situations those warnings are problematic. See #2754 for
discussion.
This is a first cut at optionally disabling the warning messages:
- adds a helper tothe EnvModule base class that encapsulates the
config file variable;
- adds a method to the base class that provides a default (empty)
code fragment for generating a warning message;
- passes the warning fragment into the bit that formats the autoload
string;
- adds specialized autload_warner() methods in the tcl and lmod
subclasses;; and finally
- touches up the autoload_format strings in the specialized classes.
