feat: Lower number of iterations when creating user (#1416)

feat: Lower number of iterations here

When we are creating 100 users in Load test in CI cluster it takes 30+
iterations to create first user. Adding 1 second delay will lower amount
of output we are getting from this function given the price of about 0.5
seconds longer user creation.
