Work in progress implementation of a recipe which migrates Hamcrest test matchers to JUnit5 test assertions.

Signed-off-by: matus.matok <matus.matok@pantheon.tech>

Added a prototype-y implementation of translation from hamcrest's equalTo to JUnit5's assertEquals. Should be easy to add more of the simple hamcrest matchers to this implementation.

\TODO the import is not being added

Another iteration of the prototype. Adapted it to be
based on the up-to-date main.
Added a proposal of how similar simple matchers could be
translated to junit assertion methods.

Added translations for matchers closeTo, containsString, empty, emptyArray, emptyIterable, emptyCollectionOf, emptyIterableOf, endsWith.
Tests need to be added for each matcher.

Added all the simple matcher-to-method translations.
Tests need to be added for each matcher.

Added a bunch of tests, to verify the correctness of each matcher-to-assertion case.

Refactored HamcrestMatcherToJUnit5 recipe, so now the whole translation is stored in one place, not scatter amongst three methods. Given the existence of RemoveIsMatcher Recipe, this recipe relies that it will never encounter is() matcher.
In similar fashion as RemoveIsMatcher, RemoveNotMatcher was added, which does exactly the same as RemoveIsMatcher, but it also stores the logical context for the nested matcher (so that it knows it was negated) in execution context.
Matchers instanceOf and isA were difficult to handle within the HamcrestMatcherToJUnit5 recipe, therefore these cases were moved to a newly added HamcrestInstanceOfToJUnit5 recipe.
