[docs] updated note on using DNS aliases for master replacement

This patch updates the warning note for the multi-master migration
section (of course, that's for 1.15 and newer versions) to bring more
clarity on what components to be restarted if not using DNS aliases.
The prior '... bringing the cluster down for maintenance ...' was not
technically correct since it's possible to perform rolling restart of
tablet servers in the cluster.

In addition, the obsolete warning note about the multi-master
migration procedure being unsafe is removed.  The new multi-master
migration procedure (for 1.15 and newer versions) is universal and
safe when migrating from N to N+1 masters.
