Deprecated Corosync command used to check the members list.

[Reymer Vargas]

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [ ] This doc is inaccurate in this way: ______
- [ ] This is a doc addition request.
- [x] I have a fix to the document that I can paste below including example: input and output.

Here's the information related to the issue:

Under "Start Corosync" section the documentation says:
```
Use the corosync-objctl utility to dump the Corosync cluster member list:

# corosync-objctl runtime.totem.pg.mrp.srp.members

...

```
... but that command is not the right one if you are using the default pkg installation on CentOS 7, instead should be:

"# corosync-cmapctl runtime.totem.pg.mrp.srp.members"

or

"# corosync-cmapctl | grep member"

This is because:

Corosync v1 --> corosync-objctl
Corosync v2 --> corosync-cmapctl

Corosync v1 --> corosync-objctl
Corosync v2 --> corosync-cmapctl

Typo ^ :D

"# corosync-cmapctl runtime.totem.pg.mrp.srp.members"

or

"# corosync-cmapctl | grep member"
