Use fixed test domain in realmdomains test

Random domain name may bring undererministic behavior. It also breaks
the test on some systems as string.lowercase is locale dependent and
can return non-ASCII letters and thus later break the unicode encoding
and raise UnicodeDecodeError.

Use a fixed domain in "test" TLD instead. This domain is guaranteed to
be not existent.
Develop.js extended

Develop.js contains code useful only for debugging. It is not part of FreeIPA
release.

Is loaded by typing require(['freeipa/develop']); in browser JS console.
It adds IPA global variable and provide easier way of loading AMD modules into
window.ipadev[providedNameOrModuleName] variable.

Allow to specify modules for which builder doesn't raise dependency error

One can specify module ids provided by other means (already built layer file) in providedMids array of build profile file's package section. Builder then ignores dependency errors for specified modules. This allows to build layers without source codes of their dependencies, with no expected errors raised.

Example:

packages:[
    {
        name: "freeipa",
        location: "freeipa",
        providedMids: [
            'dojo/_base/declare',
            'dojo/_base/lang',
            'dojo/_base/array',
            'dojo/Stateful'
            //etc
        ]
    }
],
Web UI build profile updated

freeipa.profile was updated accordingly to contain all modules in dojo layer.

This change removes expected errors during the build and therefore it won't confuse others during rpm build. It also helps during development because developer will notice real dependency errors (those not specified this way).
