### What problem does this PR solve?

Hello, our use case requires LLM agent to invoke some tools, so I made a
simple implementation here.

This PR does two things:

1. A simple plugin mechanism based on `pluginlib`:

This mechanism lives in the `plugin` directory. It will only load
plugins from `plugin/embedded_plugins` for now.

A sample plugin `bad_calculator.py` is placed in
`plugin/embedded_plugins/llm_tools`, it accepts two numbers `a` and `b`,
then give a wrong result `a + b + 100`.

In the future, it can load plugins from external location with little
code change.

Plugins are divided into different types. The only plugin type supported
in this PR is `llm_tools`, which must implement the `LLMToolPlugin`
class in the `plugin/llm_tool_plugin.py`.
More plugin types can be added in the future.

2. A tool selector in the `Generate` component:

Added a tool selector to select one or more tools for LLM:

And with the `bad_calculator` tool, it results this with the `qwen-max`
model:

### What problem does this PR solve?
This PR addresses the build and dependency issues faced by developers in
regions with poor connectivity to official Ubuntu repositories and
standard dependency sources. Currently, developers in these regions
experience slow or failed Docker builds and dependency downloads,
significantly impacting development efficiency.

### What problem does this PR solve?

This PR gives better control over how we distribute which service will
be loaded. With this approach, we can create containers to run only the
web server and others to run the task executor. It also introduces the
unique ID per task executor host, this will be important when scaling
task executors horizontally, considering unique task executor ids will
be required.

This new `entrypoint.sh` maintains the default behavior of starting the
web server and task executor in the same host.

Introduced jemalloc.
Python uses pymalloc (which is an reimplementation of gblibc malloc) to
manage RES. It has pools for small objects to avoid returning memory to
OS aggressively. My experience is: Replacing pymalloc with
[jemalloc](https://github.com/jemalloc/jemalloc) can reduce RES and
speedup task_executor.py.

For the new feature Add mssql support in the Dockerfile, I suggest
including support for msodbcsql18 for ARM64.
Based on current testing results (on macOS ARM64 environment),
msodbcsql18 needs to be installed.
I hope future Dockerfiles can incorporate a conditional check for this.
Specifically:

When $ARCH=arm64 (macOS ARM64 environment), install msodbcsql18.
In other cases (general x86_64 environment), install msodbcsql17.

This pull request implements the feature mentioned in #3322. 

Instead of manually having to edit the `service_conf.yaml` file when
changes have been made to `.env` and mapping it into the docker
container at runtime, a template file is used and the values replaced by
the environment variables from the `.env` file when the container is
started.
