fix: remove stream_state from interpolation contexts

[devin-ai-integration]

Remove stream_state from interpolation contexts as it is not thread-safe.

Requested by: natik@airbyte.io

Changes:

• Remove stream_state from all interpolation contexts in schema
• Add validation to prevent stream_state usage in interpolation
• Restore stream_state aliasing in jinja.py for backward compatibility
• Remove stream_interval parameters from components
• Update tests to use stream_interval instead of stream_state

Original prompt from natik@airbyte.io:

Hey @Devin, let's work on this issue: <https://github.com/airbytehq/airbyte-internal-issues/issues/11591>

Our goal is to make sure that:
• `stream_state` is no longer passed to low-code components for interpolation
• `stream_state` is removed from `inteprolation_context` in `declarative_component_schema.yaml`
• `stream_state`  is removed from spots where it's explicitly included in interpolation context: 
• There are 9 instances across 4 components where stream_state is explicitly included within the interpolation_context:
    ◦ AddedFieldDefintion[“properties”][“value”]
    ◦ HttpRequester[“properties”][“path”]
    ◦ HttpRequester[“properties”][“request_body_data”]
    ◦ HttpRequester[“properties”][“request_body_json”]
    ◦ HttpRequester[“properties”][“request_headers”]
    ◦ HttpRequester[“properties”][“request_parameters”]
    ◦ KeysReplace[“properties”][“old”]
    ◦ KeysReplace[“properties”][“new”]
    ◦ RecordFilter[“properties”][“condition”]
*Some more notes on how you can approach this:* 

Removing the stream_state from a component’s interpolation_context does not automatically prohibit its use. In order to fail if a connector interpolates stream_state, we’ll need to find and remove instances where stream_state is passed into the interpolator. For example, the RecordFilter component’s JinjaInterpolation is aware of stream_state because it’s passed to it via kwargs:


    def filter_records(
        self,
        records: Iterable[Mapping[str, Any]],
        stream_state: StreamState,
        stream_slice: Optional[StreamSlice] = None,
        next_page_token: Optional[Mapping[str, Any]] = None,
    ) -&gt; Iterable[Mapping[str, Any]]:
        kwargs = {
            "stream_state": stream_state, # Remove stream_state here
            "stream_slice": stream_slice,
            "next_page_token": next_page_token,
            "stream_slice.extra_fields": stream_slice.extra_fields if stream_slice else {},
        }
        for record in records:
            if self._filter_interpolator.eval(self.config, record=record, **kwargs):
                yield record

After removing all places where stream_state is passed to the interpolator, we will want to raise an exception with an appropriate error message informing the user of the change and include recommendations on ways to resolve (e.g. recommend using stream_interval instead).

To keep this change within the context of the interpolation, we can provide a similar check when evaluating an interpolated expression. This could be included in the eval method of the JinjaInterpolation class. When evaluating an expression, we can raise an AirbyteTracedException if stream_state is included within the input string. The primary benefit of this is the interpolation validation would live within the JinjaInterpolation class and the ConcurrentDeclarativeSource would not need to know about this. The primary drawbacks are that these evaluations are invoked only when needed. For example, if stream_state was interpolated within a record filter, an exception would only be raised after making a request, receiving a response, and then attempting to filter the records based on the conditional. The primary benefit of this approach is that restrictions to Jinja interpolation remain within the context of JinjaInterpolation.

Remove stream_state from here as well

There are some fundamental problems with how this PR has been designed. Primarily, the issue is that Devin has either misinterpreted or been directed incorrectly to try to inject stream_interval into every part of the codebase.

The main piece of context missing is that the stream_interval object does not actually exist across all the different components at runtime because under the hood in jinja.py, we alias stream_state into stream_interval and partition. See this block

airbyte-python-cdk/airbyte_cdk/sources/declarative/interpolation/jinja.py

Lines 89 to 96 in 74631d8

	for alias, equivalent in _ALIASES.items():
	if alias in context:
	# This is unexpected. We could ignore or log a warning, but failing loudly should result in fewer surprises
	raise ValueError(
	f"Found reserved keyword {alias} in interpolation context. This is unexpected and indicative of a bug in the CDK."
	)
	elif equivalent in context:
	context[alias] = context[equivalent]

. At worst this might bread a lot of connectors without us knowing because jinja.py won't receive the stream_state object we need to alias.

What probably needs to happen is we walk back a lot of this refactor where we're replacing stream_state with stream_interval. But the error handling with custom error messages and the YAML schema changes should be fine.
