#11003: Improve support for lazy_import inside classes

Currently, one can do:
{{{
sage: class foo(object):
... bar = LazyImport('sage.bar', 'bar')
sage: foo.bar
bar
}}}
and this works (assuming sage.bar.bar exists of course). As a
syntactic sugar, it would be nice to have lazy_import work as well, if
possible with the automatic back-insertion of the object into the
class after the actual import occurred:
{{{
sage: class foo(object):
... lazy_import('sage.bar', 'bar')
sage: type(foo.bar)
<type 'sage.misc.lazy_import.LazyImport'>
sage: foo.bar
bar
sage: type(foo.bar)
<type 'bar_type>
}}}
