Introduce testcontainers for integration tests (#1122)

`testcontainers` replaces `boltkit` as library to start docker containers.

The container should be able to start when `npm run test`, `npm run test::integration` and `npm run test::browser` are run if methods are not called from testkit.

Running the tests direct from the IDE should be also an supported usecase.

* [x] `npm run test::integration`
* [x] `npm run test`
* [x] `npm run test::browser`
* [x] Don't conflict with testkit
* [x] Start container for run tests from IDE (lite-driver)
* [ ] Start container for run tests from IDE (driver)

 ## Testing (Legacy)
 
-Tests **require** latest [Boltkit](https://github.com/neo4j-contrib/boltkit) and [Firefox](https://www.mozilla.org/firefox/) to be installed in the system.
-
-Boltkit is needed to start, stop and configure local test database. Boltkit can be installed with the following command:
-
-```
-pip3 install --upgrade boltkit
-```
+Tests **require** [Docker](https://www.docker.com/) and [Firefox](https://www.mozilla.org/firefox/) to be installed in the system.
 
 To run tests against "default" Neo4j version:
 
 ```
-./runTests.sh
+npm test
 ```
 
 To run tests against specified Neo4j version:
 
 ```
-./runTests.sh '-e 4.2.0'
+TEST_NEO4J_VERSION=5.9 npm test
 ```
 
-Simple `npm test` can also be used if you already have a running version of a compatible Neo4j server.

-For development, you can have the build tool rerun the tests each time you change

+If you already have a running version of a compatible Neo4j server, you can run:
 
 ```
-gulp watch-n-test
+TEST_CONTAINERS_DISABLED=true npm test
 ```

-If the `gulp` command line tool is not available, you might need to install this globally:
-
-```
-npm install -g gulp-cli

-### Testing on windows
-
-To run the same test suite, run `.\runTest.ps1` instead in powershell with admin right.
-The admin right is required to start/stop Neo4j properly as a system service.
-While there is no need to grab admin right if you are running tests against an existing Neo4j server using `npm test`.
