Remove most kolla-common.sh code

kolla-common.sh is mostly to handle CONFIG_INTERNAL.  Since
CONFIG_INTERNAL has been removed from the repository, we no longer
need most of this code except for set_configs.

-# The usage of the wait_for function looks like the following
-#     wait_for LOOPS_NUMBER SLEEP_TIME ARGS
-#
-# The ARGS are read and concatenated together into a single command and the
-# command is executed in a loop until it succeeds or reaches the max number of
-# attempts (LOOPS_NUMBER).
-#
-# Optional variables SUCCESSFUL_MATCH_OUTPUT and FAIL_MATCH_OUTPUT variable may
-# also be set to control if the loop exits early if the commands stdout/stderr
-# matches the supplied regex string. Consider using the `wait_for_output` and
-# `wait_for_output_unless` functions in case there is a need to check for the
-# command output.
-#
-# The script exits on failure, either when output contains string identified as
-# failure, or when it reaches a timeout.
-#
-# Examples:
-#     wait_for 30 10 ping -c 1 192.0.2.2
-#     wait_for 10 1 ls file_we_are_waiting_for
-#     wait_for 10 3 date \| grep 8
