Title: kvm-test: Adds multihost migtration test with file transfer. 

Repair bug in virt_env_process.py.

Add support for speed limiting for scp.

This test starts vm on master host. When vm is started then it starts file
transfer between vm and master host:
work: migration:
host1->vm mig_1(host1->host2)
vm->host1
checksum file
host1->vm
vm->host1 mig_2(host2<-host1)
checksum file
host1->vm
vm->host1
checksum file mig_3(host1<-host2)
... ...
... ...
... ...
host1->vm ...
vm->host1 ...
checksum file mig_migrate_count(host2<-host1)

end:
check all checksum with orig_file checksum
