Sd card not tested (BugFix)

[fernando79513]

WARNING: This modifies com.canonical.certification::sru-server

Description

This ticket introduces some changes to the disk tests.
The first of them is to include SD cards into the "DISK" category so we can run disk performance tests in devices that have root mounted on an SD card. This behavior was purposely ignored before.

if self.driver:
...
    # Only consider eMMC internal drives as DISK.
    # As it's not possible to distinguish them from simple MMC
    # removable storage, only those with a partition mounted as /
    # will be considered.
    # To avoid categorizing SD cards as main storage and run heavy
    # tests on them (e.g on a pandaboard) only devices with the udev
    # property MMC_TYPE == MMC are accepted.
    if self.driver.startswith("mmc"):
        if self._mmc_type == "MMC" and find_pkname_is_root_mountpoint(
            self.name, self._lsblk
        ):
            return "DISK"
        else:
            return "CARDREADER"

But we have decided to include also SD cards into the "DISK" category so the disk tests are run also in these devices
We should keep in mind that these tests, particularly the storage test, put stress on the SD cards, which could potentially reduce their lifespan.

The second one is to ignore some disks for certain types of tests:

• Disks with less than 2MB of memory are ignored for reading tests
• mtdblock disks are ignored for storage tests.

We discussed moving the disk-detecting logic to a separate resource instead of using "udevadm.py", but I think we can do that in a follow-up ticket.

Tests

The tests have been run in a laptop and in a Xilinx device with the root mounted in the SD card:
