Add cpu resize ability upon upcall communication channel. Runtime could
use ResizeVcpu VmmAction and pass the desired vCPU number to the
Dragonball hypervisor.
Dragonball will trigger the device manager service in guest kernel's
upcall server to do cpu resize.

Since the upstream rust-vmm is changing its dependency style towards
caret requirements in these days (more information:
rust-vmm/vm-memory#199) and it breaks Dragonball compilation frequently.
rust-vmm is expected to finish the changes this week and in order to not
break Kata CI due to Dragonball's compilation error, we will add
Cargo.lock file into /src/dragonball first and remove it later when
rust-vmm is stable.

Since the upstream of vmm-sys-utils upgraded to 0.11.0, some crates
automatically upgrade to v0.11.0, and some stay at v0.10.0 ( depending
on how they write version dependency in Cargo toml` which causes the
compile error in runtime-rs.
In order to fix this problem, we need to upgrade all vmm-sys-util
dependencies in runtime-rs to v0.11.0.

The cargo patch in the cargo.toml seems to cause the whole runtime-rs
building time longer and also makes it harder to build runtime-rs in an
environment without the network
We should delete all patches from the cargo.toml file and publish all
the crates that was once patched.
