AWS lambda Collector needs enhancements

[zerolaser]

What would you like to be added:

• AWS Lambda UI should display total number of innvocation count.

• AWS Lambda UI Should display memory size.

• AWS Lambda collector should check if the function is choosing the right memory size ?

Why is this needed:

• This will help us know the most innvocations used by a lambda function.

• Will help us identify which lambda function used max memory size.

• right memory size predictor will help us choosing the right size for the function.
