tests(parameters): add comments to SecretsProvider e2e test (#1282)
* fix import to src, instead of lib * clearing cache to fix forceFetch test case * add more comments, create dedicated resource for test 7 * Update packages/parameters/tests/e2e/secretsProvider.class.test.functionCode.ts --------- Co-authored-by: Andrea Amorosi <dreamorosi@gmail.com>

* Collection of e2e tests for SecretsProvider utility.
29+
*
30+
* Test 1: create a secret with plain text value, fetch it with no additional options
31+
* Test 2: create a secret with json value, fetch it using `transform: 'json'` option
32+
* Test 3: create a secret with base64 encoded value (technicaly string), fetch it using `transform: 'binary'` option
33+
* Test 4: create a secret with json value and secret name ends with .json, fetch it using `transform: 'auto'` option
34+
* Test 5: create a secret with base64 encoded value (technicaly string) and secert name ends with .binary, fetch it using `transform: 'auto'` option
35+
* Test 6: create a secret with plain text value, fetch it twice, check that value was cached, the number of SDK calls should be 1
36+
* Test 7: create a secret with plain text value, fetch it twice, second time with `forceFetch: true` option, check that value was not cached, the number of SDK calls should be 2
37+
*
38+
* For tests 6 and 7 we use our own AWS SDK custom middleware plugin `sdkMiddlewareRequestCounter.ts`
39+
*
40+
* Adding new test:
41+
* Please keep the state clean, and create dedicated resource for your test, don't reuse resources from other tests.
42+
* Pass the necessary information to lambda function by using enviroment variables
43+
* Make sure to add the right permissions to the lambda function to access the resources. We use our `ResourceAccessGranter` to add permissions.
