migration_v2 (#38)

bulk write after docs was scrolled complete

update default config with migration dispatcher

add bulk parameter idle_timeout_in_seconds, slice_size

clear queue before creating pipeline

check instance available when task state is running

add check_instance_available config for migration dispatcher

get migration task progress info by index_name_unique(index_name+doctype)

get instance list only by gateway

get migration task progress info from es and instance pipeline context

rewrite logic of handling running migration major task

calc complete time in api getDataMigrationTaskOfIndex

init
