target: Ensure consistency between target.execute() and conn.execute()

Commit 511d4781646b ("exceptions: Classify transient exceptions")
introduced a "will_succeed" argument in target.execute(). This argument
is then passed down to conn.execute(). However, since it is not
labelled, this argument happens to overwrite the "strip_colors" argument
of conn.execute because of its position in the list of parameters.

Fix this by labelling the parameters given to conn.execute(). While at
it, introduce a "strip_colors" parameters for target.execute() hence
keeping the APIs consistent.
