Description:

When I created a cluster, I had to only enter the master key once. Now I made a typo and I don't know the key anymore.

How to repeat:
```
mysql-js> cluster = dba.createCluster('plam')
A new InnoDB cluster will be created on instance 'root@mysql3:3306'.

When setting up a new InnoDB cluster it is required to define an administrative
MASTER key for the cluster. This MASTER key needs to be re-entered when making
changes to the cluster later on, e.g.adding new MySQL instances or configuring
MySQL Routers. Losing this MASTER key will require the configuration of all
InnoDB cluster entities to be changed.

Please specify an administrative MASTER key for the cluster 'plam': 
Creating InnoDB cluster 'plam' on 'root@mysql3:3306'...
Adding Seed Instance...

Cluster successfully created. Use Cluster.addInstance() to add MySQL instances.
At least 3 instances are needed for the cluster to be able to withstand up to
one server failure.

<Cluster:plam>
mysql-js> 
```

Suggested fix:

It would be great if the master key is asked twice so I am less likely to make a typo as now I have to remove and recreate the cluster

Hello Kenny,

Thank you for the report and feedback!

Hi Umesh
 
 
 
Even your request was completely valid (and a good one) you may have noted we
changed the security model, we are no longer using the Master Key approach
and so this request goes obsolete.
 
 
 
Thank you so much for your help testing the shell.
