Update the tasks to check the availability of the VIP address

[vitabaks]

Update task "Wait for the cluster IP address (VIP) is running" (if cluster_vip is defined)

• Add 'ignore_errors: true' to show the error and continue the playbook execution
  • In some environments with strict SSH access rules, checking the availability of an IP address over an SSH port may not work. To handle such cases, we added 'ignore_errors' to the task "Wait for the cluster IP address (VIP) is running" to continue the playbook execution even if the IP address check fails.
• Use the pgbouncer_listen_port (or postgresql_port if 'pgbouncer_install' is 'false') to check the availability of the VIP address. Otherwise, it defaults to SSH port, applicable during deployment when the database is not yet available.
• Change the check timeout from 2 minutes to 30 seconds
