 Description   

Columnstore is able to use domain names since 1.1.6
MCOL-1551

Sometimes bad or slow DNS Reolver cause
"MessageQueueClient :: setup (): unknown name or service"
also for IP-addresses.

Also for avoiding overhead for IP-address only configuration for performance reasons or/and
make Columnstore more independent from DNS Reolver adding a config value

<skip_name_resolve>n</skip_name_resolve>

This is inspired by the same global variable for MariaDB

skip_name_resolve

Default is "N"

A workaround could be to add all server in the Columnstore cluster in

/etc/hosts

Also configure nsswitch.conf with

hosts: files dns

In this case GETADDRINFO() checks /etc/hosts first.

Not necessary after convergence.
