Redis.io code examples (#3418)

* Added a simple SET and GET example * Added a meta data file. Needs to be removed as soon as we added this into the files themselves. * Update SetGetTest.java Added output comments * Update SetGetTest.java Changed the output to be more use case specific. * Wrapped the code by a test suite to keep it self-explaining * Update SetGetExample.java * Update SimpleCommandsTestSuite.java Added some comments * Update SimpleCommandsTestSuite.java Added some additional comments about how to combine code samples with JUnit tests. * Update SetGetExample.java * Update example.json Testing with wildcard search for examples. * Update SetGetExample.java Hiding the end of the file by default * Update SetGetExample.java * Update SetGetExample.java * Test annotations are now ignored by the doc parser * Changed the package name * Remove indentation * New 'Example' file name rule * Revert indentation in SetGetExample.java * skeleton of documentation tests * Make doctests runnable in CI - Move doctests to test folder to make them discoverable by JUnit - Add doctests profile - Fix doctests workflow * Add Search QuickStart to doctests * Fix workflow file * Bump Java version to 11 * Exclude doctests from testCompile * Give up on 2 Java versions support * surefire plugin 3.0.0 * fix updated doc package --------- Co-authored-by: David Maier <60782329+dmaier-redislabs@users.noreply.github.com> Co-authored-by: M Sazzadul Hoque <7600764+sazzad16@users.noreply.github.com> Co-authored-by: Chayim I.
