Functional tests for trigger-crash-dump (microversion 2.17)

It's a resource-consuming task to implement full-flow (up to getting
and reading a dump file) functional test for trigger-crash-dump.
We need to upload Ubuntu image for booting an instance based on it,
and to install kdump with its further configuring on this instance.

Here, the "light" version of functional test is proposed.
It's based on knowledge that trigger-crash-dump uses a NMI injection,
and when the 'trigger-crash-dump' operation is executed,
instance's kernel receives the MNI signal, and an appropriate
message will appear in the instance's log.

Wait_for_server_os_boot() method has been added to ClientTestBase
to check if instance's operating system  is completely booted.

The _create_server() method has been removed since the change
which puts this method to the base test class has been merged.
