Get parameter by name support on Montoya

[cyal1]

http parameters can be quite flexible, with possibilities of having multiple identical parameters, empty name, empty value, and other complex scenarios.

I have designed the following functions to easily retrieve parameter values from a request:

getParamByName(paramList, key, locate, index=0)
getBodyParamByName(paramList, key, locate=HttpParameterType.BODY, index=0)

The first parameter is the parameter list, the second parameter is the parameter name, and the third parameter is the parameter location. By default, it searches in the BODY location. The last parameter is the index, which defaults to returning the first found value. If the user specifies n, it returns the value of the n-th found key. If the iteration completes without finding the specified index, it returns the value of the last found index. If no index is found at all, it returns an empty string.

You can use a similar design to retrieve specific headers.
Thanks.
