Create cow repository for USD estimation based on native price (+tests)

[anxolin]

This PR will calculate the USD price for any token by using native price endpoint of CoW API

This PR includes the implementation of the logic (basically gets native price of USDC and the token and compare it to each other)

The tests asserts that it works for some representative case: WETH (because it has 18 decimals, and USDC has 6, so we make sure it takes decimals into account.

It will test 404 case when you pass something is not a token. --> will return null

It will test 400 case

• Will test for example when the tokens are not supported --> we return null
• Other 400 errors will be throwing (I tested this too). It will try to use the description and error type returned by the backend

It will also test that any other error that is not a 200, then it will throw --> tests the 418 I'm not a teapot code

Extra

This PR also includes

• Improves the setup of IoC (now all apps and libs will set it up as part of the jest config). They will all use a shared setup script
• Adds 50% error tolerance for the coingecko integration test (it was failing at some point)
