[keycloak-dev] Renaming testsuite/integration to testsuite/integration-deprecated

[Stian Thorgersen]

I would like to rename testsuite/integration to
testsuite/integration-deprecated. This is to make it clear to external
contributors that the testsuite is deprecated and new tests should be added
to testsuite/integration-arquillian.

I would also like to rename testsuite/integration-arquillian
to testsuite/integration.
