happened twice with test test_new_sc_new_rbd_pool[3-aggressive-Immediate-Bound]

It also happened a few times with test_multiple_sc_one_pool: https://reportportal-ocs4.apps.ocp-c1.prod.psi.redhat.com/ui/#ocs/launches/632/20572/987161/987181/log, https://reportportal-ocs4.apps.ocp-c1.prod.psi.redhat.com/ui/#ocs/launches/632/20461/983578/983598/log etc

upd:
all tests mentioned are failing within this code block:

` def page_has_loaded(
self, retries=5, sleep_time=2, module_loc=("html", By.TAG_NAME)
):
"""
Waits for page to completely load by comparing current page hash values.
Not suitable for pages that use frequent dynamically content (less than sleep_time)

    Args:
        retries (int): How much time in sleep_time to wait for page to load
        sleep_time (int): Time to wait between every pool of dom hash
        module_loc (tuple): locator of the module of the page awaited to be loaded
    """

    @retry(TimeoutException)
    def get_page_hash():
        """
        Get dom html hash
        """
        self.check_element_presence(module_loc[::-1])
        dom = self.get_element_attribute(module_loc, "innerHTML")
        dom_hash = hash(dom.encode("utf-8"))
        return dom_hash

    page_hash = "empty"
    page_hash_new = ""

    # comparing old and new page DOM hash together to verify the page is fully loaded
    retry_counter = 0
    while page_hash != page_hash_new:
        if retry_counter > 0:
            logger.info(f"page not loaded yet: {self.driver.current_url}")
        retry_counter += 1
        page_hash = get_page_hash()
        time.sleep(sleep_time)
        page_hash_new = get_page_hash()
        if retry_counter == retries:
            logger.error(
                f"Current URL did not finish loading in {retries * sleep_time}"
            )
            self.take_screenshot()
            return
    logger.info(f"page loaded: {self.driver.current_url}")

`

it seems to be overwhelming to get page has every 2 seconds
retry_counter += 1 page_hash = get_page_hash() time.sleep(sleep_time) page_hash_new = get_page_hash()

1. we need to minimize calling page_has_loaded, especially on Page Objects, similarly to StorageSystemTab(DataFoundationTabBar, CreateResourceForm) -> just remove CreateResourceForm.init from StorageSystemTab constructor
2. reduce volume of page hash we are copying, maybe remove footer, header, static elements
3. increase mem limits to SeleniumDriver
