tests reorganization and add main test script (#307)

* tests reorganization and add main test script

1 - reorganization of the tests folder
    tests having same category live in a subfolder

2 - expose pytest capabilities to users
    currently, tox is masking all pytest features and only
    expose what we specify in tox.ini file
    since tox is only here to manage the test environment
    it should be transparent to the users for tests execution
    and management. the users should be able to take full advantage
    of what pytest offers.
    we introduced a new script tdtest that hides tox and exopose
    all pytest features to users

* Update tests/README.md

add direct boot methods and UKI (#296)

* add more methods to boot a TD

we have different methods to boot a TD
for now, we use the traditional method that consists of passing
the ubuntu image to qemu
however, we have other ways to boot a TD:
- direct boot : by providing the kernel and initrd to qemu
- UKI : by providing the Unified Kernel image (that contains the kernel and initrd)

each method generates a different event log journal because the boot chain
involves less or more components that generate event logs

it is important to evaluate which is the best boot method to have a short
and consistent event log journal to make sure that remote attestation
is reliable

tests : move packages used by TDX test to tdx-testing (#269)

until now, the packages (vsock-iperf) are uploaded in the testing PPA
this testing PPA is a temporary PPA used for various debugging purposes
and can be removed at any time, we created a new PPA dedicated to host
test packages for TDX (tdx-testing)

this patch make the TDX tests use this new PPA

Fix typo (#203)

improvement setup configuration management (#104)

* improve setup scripts configuration

put all variables in a config file
clean up setup scripts in the guest at the end

* allow downgrade for attestation packages

Add list command to td_virsh_tool (#55)

To be able to list current VMs, this is important to see the forwarding ports
for ssh connection

Merge main-next to main to enable attestation setup (#51)

* Add attestation setup script

* Check script is run with root privileges

* Add trust authority client in setup guest script

* Add build-essential to compile tdx-attest

* Validate and clean up attestation instructions (#48)

* Validate and clean up attestation instructions

* Use more explicit naming of attestation scripts

* Remove sudo from commands in guest

* Remove useless script setup-attestation.sh

* Use tdx-release PPA that contains released components (#49)

* Improve attestation setup script (#50)

* setup-attestation-host.sh : do not set user and group for /dev/sgx_provision

the udev rules will take care of it

* Remove README section on use_secure_cert

with the version 1.18-0ubuntu2 of libsgx-dcap-default-qpl
the use_secure_cert is set to false by default

* Add reboot instruction in README

after the setup script run for attestation, we need to reboot
to have the right owner & group for /dev/sgx_provision (from udev rule)

Remove useless apt cmd and IMA config in TDX image creation (#36)

The TDX setup process is nice and won't break the apt system, so
"apt install --fix-broken" is redundant.
Also remove IMA parameters from guest kernel cmdline to avoid confusion.
Enabling TDX doesn't require kernel IMA at all.
