Remove some escape chars

Related to #4234 (closed)

This PR review the use of \r and ANSI char and try to deal in better way with it

• Use helper from from bliss.shell.formatters.ansi instead of hardcoded chars
• Use bliss.common.user_status_info when ever it is possible
• Remove some \r which was not needed
• It also fix and improve the redisplay of bliss.common.user_status_info which was broken

from bliss.common.user_status_info import status_message
import gevent
with status_message() as update:
    update("Pif")
    gevent.sleep(1)
    update("Paf")
    gevent.sleep(1)
    update("Pouf")
    gevent.sleep(1)
    update("Toc")
    gevent.sleep(1)
    update("He fall down")
    gevent.sleep(1)

The following will require more work, for another PR

• bliss/controllers/diffractometers/diff_base.py <- we should use umove, with dedicated params if needed
• bliss/controllers/speedgoat/speedgoat_utils.py <- we should use a dedicated textblock for that
