Refine implementation of mount by:
- log message with `path.display()` instead of `{:?}`
- add prefix "_" to unused variables
- pass by reference instead of by value to avoid creating redundant
array
- exactly matching prefix "fsgid=" instead of "fsgid"
- avoid redundant clone() operations

Refine style of code related to sandbox by:
- remove unnecessary comments for caller to take lock, we have already taken
`&mut self`.
- change "*count < 1 " to "*count == 0", `count` is type of u32.
- make remove_sandbox_storage() to take `&mut self` instead of `&self`.
- group related function to each others
- avoid search the map twice in function find_process()
- avoid unwrap() in function run_oom_event_monitor()
- avoid unwrap() in online_resources()

These calls cause two extra atomic instructions each time they're used,
one to increment and another one to decrement the refcount.
Since we don't need them because the referred value is guaranteed to
outlive the function, remove the calls.

currently when fsGroup is used with direct-assign, kata agent
recursively changes ownership and permission for each file including
symlinks. However the problem with symlinks is, the permission of
the symlink itself may not be same as the underlying file. So while
doing recursive ownership and permission changes we should skip
symlinks.

Issue #4747 and pull request #4748 fix exec hang issues where the exec
command hangs when a process's stdout is not closed. However, the PR might
cause the exec command not to work as expected, leading to CI failure. The
PR was reverted in #7042. This PR resolves the exec hang issues and has
undergone 1000 rounds of testing to verify that it would not cause any CI
failures.

Using an initrd and setting KATA_INIT=yes meaning we're using the kata-agent
as the init process we need to make sure that the agent is not segfaulting
if mounts are already happened. Some workloads need to configure several
things in the initrd before the kata-agent starts which involves having
/proc or /sys already mounted.

Having a function allows for better error messages from the type checker
and it makes it clearer to callers what can happen. For example:
is_allowed!(req);
Gives no indication that it may result in an early return, and no simple
way for callers to modify the behaviour. It also makes it look like
ownership of `req` is being transferred.
On the other hand,
is_allowed(&req)?;
Indicates that `req` is being borrowed (immutably) and may fail. The
question mark indicates that the caller wants an early return on
failure.

Since it is never modified, it doesn't really need a lock of any kind.
Removing the `RwLock` wrapper allows us to remove all `.read().await`
calls when accessing it.
Additionally, `AGENT_CONFIG` already has a static lifetime, so there is
no need to wrap it in a ref-counted heap allocation.

Some vmms, such as dragonball, will actively help us
perform online cpu operations when doing cpu hotplug.
Under the old onlineCpuMem interface, it is difficult
to adapt to this situation.
So we modify the semantics of nb_cpus in onlineCpuMemRequest.
In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
semantics become that the number of online CPUs in the guest
needs to be guaranteed.

- Switch kata-ctl from eprintln!()/println!() to structured logging via
the logging library which uses slog.
- Adds a new create_term_logger() library call which enables printing
log messages to the terminal via a less verbose / more human readable
terminal format with colors.
- Adds --log-level argument to select the minimum log level of printed messages.
- Adds --json-logging argument to switch to logging in JSON format.
