// CreateInstallationResources creates both CheInstallation and TektonInstallation resources. If they already exist then it ignores it.
// Before the actual creation it also tries to get the Subscription that was created for codeready-toolchain-operator.
// If such a subscription is found, then it sets it as ownerReference for the Installation resources. The reason is
// that we need to remove(uninstall) the Che and Tekton operators when the codeready-toolchain-operator is being uninstalled,
// which means their respective Subscriptions are also removed. Thanks to the garbage collector it will ensure that both
// Che and Tekton operators will be uninstalled too.
