Implementation of Google PaLM connector with text completion and an
example file to demonstrate its functionality.
Closes #1979

### Description

<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->

1. Implemented Google Palm connector with text completion 
2. Added example file to ```python/samples/kernel-syntax-examples```
3. Added integration tests with different inputs to kernel.run_async
4. Added unit tests to ensure successful initialization of the class and
successful API calls
5. 3 optional arguments (top_k, safety_settings, client) for
google.generativeai.generate_text were not included. See more
information about the function and its arguments:
https://developers.generativeai.google/api/python/google/generativeai/generate_text

I also opened a PR for text embedding and chat completion #2258

- [x] All unit tests pass, and I have added new tests where possible
- [x] I didn't break anyone 😄

Currently no warnings, there was 1 warning when first installing genai
with `poetry add google.generativeai==v0.1.0rc2` from within poetry
shell: "The locked version 0.1.0rc2 for google-generativeai is a yanked
version. Reason for being yanked: Release is marked as supporting Py3.8,
but in practice it requires 3.9". We would need to require later
versions of python to fix it.

### Description
**What's new:**
1. Implemented Google Palm connector with chat completion and text
embedding
2. Added 3 example files to `python/samples/kernel-syntax-examples`
3. The example files show PaLM chat in action with skills, memory, and
just with user messages. The memory example uses PaLM embedding as well
5. Added integration tests to test chat with skills and embedding with
kernel.memory functions
6. Added unit tests to verify successful class initialization and
correct behavior from class functions
  
**There are some important differences between google palm chat and open
ai chat:**

1. PaLM has two functions for chatting, `chat` and `reply`. The chat
function in google's genai library starts a new conversation, and reply
continues the conversation. Reply is an attribute of the response object
returned by chat. So an instance of the `GooglePalmChatCompletion` class
needs a way to determine which function to use, which is why I
introduced a private attribute to store the response object. See
https://developers.generativeai.google/api/python/google/generativeai/types/ChatResponse
2. PaLM does not use system messages. Instead, the chat function takes a
parameter called context. It serves the same purpose, to prime the
assistant with certain behaviors and information. So when the user
passes a system message to `complete_chat_async`, it is passed to `chat`
as the context parameter.
3. Semantic memory works with the chat service as long as the user
creates a chat prompt template. The prompt containing the memory needs
to be added to the chat prompt template as a system message. See
`python\samples\kernel-syntax-examples\google_palm_chat_with_memory.py`
for more details. If the only purpose of `complete_async` in
`GooglePalmChatCompletion` is to send memories + user messages to the
chat service as a text prompt, then `complete_async` is not fulfilling
its intended purpose. A possible solution would be to send the text
prompt as a request to the text service within `complete_async`.
