In many application repositories, we have an environmental variable validation engine. It is typical for this engine to have code that needs to transform incoming environmental variable values to values of a specific type. These tasks are repeatable in many projects:
lidofinance/ethereum-validators-monitoring#224
https://github.com/lidofinance/node-operators-widget-backend-ts/pull/41
lidofinance/lido-keys-api#216
It makes sense to move this repeated code from many projects to some common place.
The new "transform" module introduced in this PR collects these common transformation functions.
