[QE] Add github action for linux PR check with machine from testing farm

[lilyLuLiu]

#4305
The self-hosted runner have been added. Now we can use it to reserve machine for linux PR check

[adrianriobo]

There is a new requirement to use a jump host from self hosted runner, the jump will be accomplished using https://github.com/adrianriobo/deliverest/issues/9

The machine reserved from the Testing Farm is root user, while crc is not allowed to run with root.
I tried to create a user and then switch to the user in the testing container, but it did not work.
Will ask the Testing Farm team whether supports reservation non-root machines.

What is the error, can you put the logs?

@praveenkumar Hi, the issue has been solved: Copy the root authorized_keys file to the newly created user. Then the reserved machine could be accessed by the new user.
