Persist available tools from a Tool repository (#2851)

* feat: add capability to see and expose public Tool classes

* feat: persist available Tools from repository on publish

* ci: ignore explictly templates from ruff check

Ruff only applies --exclude to files it discovers itself. So we have to skip manually the same files excluded from `ruff.toml`

* sytle: fix linter issues

* refactor: renaming available_tools_classes by available_exports

* feat: provide more context about exportable tools

* feat: allow to install a Tool from pypi

* test: fix tests

* feat: add env_vars attribute to BaseTool

* remove TODO: security check since we are handle that on enterprise side
