Added resource Requests values for St2 Pods

[arms11]

Closes #5
The values are added based on production monitoring average base on during peak/off-peak hours.
Please note: While I have not been able to test this in minikube due to unrelated reasons, below is the resource utilization of the 3 nodes cluster with t3.large (2 CPUs/8GB Memory) spec.

NAME                             CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%
ip-192-168-137-84.ec2.internal   428m         22%    2587Mi          36%
ip-192-168-171-99.ec2.internal   279m         14%    3048Mi          42%
ip-192-168-99-86.ec2.internal    237m         12%    2640Mi          37%
