* les: move execqueue into utilities package
execqueue is a util for executing queued functions
in a serial order which is used by both les server
and les client. Move it to common package.
* les: move randselect to utilities package
weighted_random_selector is a helpful tool for randomly select
items maintained in a set but based on the item weight.

common package as the second step for les separation.
