Move code samples to master branch (#3271)

Move the code samples used for documentation into the master branch,
so they sit next to the code they document.

+# Command examples for redis.io
+
+## How to add an example
+
+Create regular python file in the current folder with meaningful name. It makes sense prefix example files with
+command category (e.g. string, set, list, hash, etc) to make navigation in the folder easier. Files ending in *.py*
+are automatically run by the test suite.
+
+### Special markup
+
+See https://github.com/redis-stack/redis-stack-website#readme for more details.
+
+## How to test examples
+
+Examples are standalone python scripts, committed to the *doctests* directory. These scripts assume that the
+```requirements.txt``` and ```dev_requirements.txt``` from this repository have been installed, as per below.
+
+```bash
+pip install -r requirements.txt
+pip install -r dev_requirements.txt
+pip install -r doctests/requirements.txt
+```
+
+Note - the CI process, runs the basic ```black``` and ```isort``` linters against the examples. Assuming
+the requirements above have been installed you can run ```black yourfile.py``` and ```isort yourfile.py```
+locally to validate the linting, prior to CI.
+
+Just include necessary assertions in the example file and run
+```bash
+sh doctests/run_examples.sh
+```
+to test all examples in the current folder.
