Add type checking for config props

[mihaiblaga89]

Is your feature request related to a problem? Please describe. Enforce type checking when parsing the configs.

Describe the solution you'd like Either have another argument in getConfigProp specifying what type of data to expect, or separate it into several functions, like getConfigString, getConfigBool. This will throw an error if, for example, you specify something else than true or false in a prop that's being passed through getConfigBool.

getConfigProp is now TS generics based method which utilizes autogenerated TS schema definitions to extract correct type
