Memory and CPU Requests/Limit Check to be user input

[sttor]

As of now, we only check if the memory or CPU limit is set or not, better would be

1. To take user input to validate the memory and CPU limits.
2. Translate "M" and "m" for CPU and G, Gi, Mi, and M for RAM. Better to use 1000 conversion units for both.
