[buid-team] Add artifacting for npm\bower\pip

[Aleksey Zvyagintsev]

Currently is no possibility to prepare fix for building iso w\o external packages fetching, like pip\npm\bower, in short period of time.

As it was discussed internally between MOS\FUEL team members, propose to implement artifact preparing like workaround:

Flow:
1)inside config.mk enable flag like-
-save_upgrade_pip.tgz (now, needed only for upgrade module)
-save_node_modules.tgz (now, needed only for rpm/nailgun module)
-save_bower_components.tgz (now, needed only for rpm/nailgun module)
2)Build iso somewhere with access to inet. build job populate *tgz.
3)On isolated build iso env - pass predefined tgz files like config.mk parameters.

Forwarded bug to Fuel build team.

all npm\bower modules were built as rpm packages

[Aleksey Zvyagintsev (azvyagintsev)]

confirmed on isolated building

Moved to non-release due to knowledge, that we haven't requirement to deliver our build system as dedicated product or part of it.
