uffizzi install: Increase IP check tries

[gadkins]

When installing Uffizzi via uffizzi install, it sometimes happens that the IP address returned from this command is 'unknown'. This occurs because there is a timeout, likely because the IP address from the cloud provider is not yet ready. We should increase the tries from 30 to 60. See relevant code here:

uffizzi_cli/lib/uffizzi/cli/install.rb

Lines 74 to 98 in 77ad3d7

	def wait_ip
	spinner = TTY::Spinner.new('[:spinner] Waiting IP addess...', format: :dots)
	spinner.auto_spin
	ip = nil
	try = 0
	loop do
	ip = InstallService.get_controller_ip(namespace)
	break if ip.present?
	if try == 30
	spinner.error
	return 'unknown'
	end
	try += 1
	sleep(2)
	end
	spinner.success
	ip
	end
