Dependencies between e2e tests lead to cascading failures

[m1kola]

In this test we delete the test catalog:

operator-controller/test/e2e/install_test.go

Lines 145 to 146 in 7f61f6d

	// Delete the catalog first
	Expect(c.Delete(ctx, operatorCatalog)).To(Succeed())

And later recreate it here:

operator-controller/test/e2e/install_test.go

Lines 163 to 164 in 7f61f6d

	operatorCatalog, err = createTestCatalog(ctx, testCatalogName, os.Getenv(testCatalogRefEnvVar))
	Expect(err).ToNot(HaveOccurred())

The issue is that - if any of the assertions before catalog recreation fails all tests which use the test catalog will also fail.
