Optimize Rally imports to reduce start time
* Load plugins only if they are required This reduce a lot starting time of Rally and will allows us to do online bash completition As well it cleans up project structure a lot, e.g. all plugins are loaded in single place + we don't have strange code in cliutils * Replace rally.ui.utils to not import mako and remove all code on module level * Make Rally DB lazy inited * Import plugins during test run ---- The best way to test changes in start up time is to compare "time rally version" e.g.: before this patch: $ time rally version 0.0.5 real 0m0.397s user 0m0.299s sys 0m0.089s after this patch: 0.0.5 real 0m0.281s user 0m0.200s sys 0m0.077s Change-Id: Ibec2e6da66a1304730e801de307df7a1da68d51f
