#148 Replaced Master and Slave with Primary and Replica where applicable

[nastena1606]

The labels, commands and command outputs keep master and slave. Added a note about using master and slave to replication page

I also see a reference in replconf.md.
In replication.md, we should include references to primaryauth as the preferred alternative to mastauth.

All the updates look good, mostly suggesting some additional changes.

Awesome. Sorry I didn't review this. I just noticed the note "A note about the word slave used in this man page" is on various pages, for example on commands/role.md. It should probably be updated to the version you used in the migration guide, the version mentioning master and slave.

I did a git grep:

$ git grep 'about the word'
commands/cluster-nodes.md:**A note about the word slave used in this man page and command name**: If not for Redis OSS compatibility, the Valkey project does not use the word slave. Unfortunately in this command the word slave is part of the protocol, so we'll be able to remove such occurrences only when this API will be naturally deprecated.
commands/cluster-slaves.md:**A note about the word slave used in this man page and command name**: If not for Redis OSS compatibility, the Valkey project does not use the word slave. Please use the new command `CLUSTER REPLICAS`. The command `CLUSTER SLAVES` will continue to work for backward compatibility.
