Description of problem:
For products with large component lists the create bug page loads slowly.

There seems to be 2 causes of this.

1: The components are cached in enter_bug.cgi.

2: The components are cached in template/en/default/bug/create/create.html.tmpl when rendering bug and attachment flags.

#1 can be removed, it is unnecessary as the components are fetched using ajax on the form.

#2 requires reviewing Bugzilla::Product::flag_types, this method caches all the component specific flags. It looks like this might not be required for entering bugs, so it might be possible to add a parameter to this method to bypass component caching. Alternatively it might simply be possible to disable the component caching code, this would require confirmation.
