[ssassi]

This PR adds the possibility of creating streamlit apps:

Python

# Creating a Streamlit app from a stage
streamlit_stage = Streamlit(
    name="my_db.my_schema.my_streamlit",
    from_="@my_stage",
    main_file="app.py",
    title="My Streamlit App",
    query_warehouse="my_warehouse",
    comment="A sample Streamlit app from a stage",
    tags={"project": "demo"}
)

# Creating a Streamlit app from a Git repository
streamlit_repo = Streamlit(
    name="my_streamlit",
    from_="https://github.com/user/repo.git",
    version="main",
    main_file="app.py",
    title="Repo Streamlit App",
    owner="SYSADMIN"
)

YAML

streamlits:
  - name: my_db.my_schema.my_streamlit
    from: "@my_stage"
    main_file: "app.py"
    title: "My Streamlit App"
    query_warehouse: "my_warehouse"
    comment: "A sample Streamlit app from a stage"
