attempt to fix a race condition in BSC test's f_ts_dyn_mode_get
Add two helper functions which retry a VTY command until the
result matches a regular expression or a configurable timeout
expires.
Use these functions in BSC test's f_ts_dyn_mode_get, which has
seen sporadic failures due to a race condition during channel
reconfiguration, in order to hopefully close this race.
