Cognite-sdk

Added
- `root_asset_ids` parameter for time series list.

Changed
- Formatted output in jupyter notebooks for `SequenceData`.
- `retrieve_latest` function in theDatapoints API extended to support more than 100 items.
- Log requests at DEBUG level instead of INFO.

Changed
- Disabled automatic handling of cookies on the requests session objects

Fixed
- `to_pandas` method on CogniteResource in the case of objects without metadata

Added
- `limit` parameter on sequence data retrieval.
- Support for relationships exposed through experimental client.
- `end` parameter of sequence.data retrieval and range delete accepts -1 to indicate last index of sequence.

Changed
- Output in jupyter notebooks is now pandas-like by default, instead of outputting long json strings.

Fixed
- id parameters and timestamps now accept any integer type including numpy.int64, so values from dataframes can be passed directly.
- Compatibility fix for renaming of sequences cursor and start/end parameters in the API.

Added
- `complete` parameter on `datapoints.retrieve_dataframe`, used for forward-filling/interpolating intervals with missing data.
- `include_aggregate_name` option on `datapoints.retrieve_dataframe` and `DatapointsList.to_pandas`, used for removing the `|<aggregate-name>` postfix on dataframe column headers.
- datapoints.retrieve_dataframe_dict function, which returns {aggregate:dataframe} without adding aggregate names to columns
- source_created_time and source_modified_time support for files

Added
- New method create_hierarchy() added to assets API.
- SequencesAPI.list now accepts an asset_ids parameter for searching by asset
- SequencesDataAPI.insert now accepts a SequenceData object for easier copying
- DatapointsAPI.insert now accepts a Datapoints object for easier copying
- helper method `cognite.client.testing.mock_cognite_client()` for mocking CogniteClient
- parent_id and parent_external_id to AssetUpdate class.

Changed
- assets.create() no longer validates asset hierarchy and sorts assets before posting. This functionality has been moved to assets.create_hierarchy().
- AssetList.files() and AssetList.events() now deduplicate results while fetching related resources, significantly reducing memory load.

Added
- files.create() method to enable creating a file without uploading content.
- `recursive` parameter to raw.databases.delete() for recursively deleting tables.

Changed
- Renamed .iteritems() on SequenceData to .items()
- raw.insert() now chunks raw rows into batches of 10,000 instead of 1,000

Fixed
- Sequences queries are now retried if safe
- .update() in all APIs now accept a subclass of CogniteResourceList as input
- Sequences datapoint retrieval updated to use the new cursor feature in the API
- Json serializiation in `__str__()` of base data classes. Now handles Decimal and Number objects.
- Now possible to create asset hierarchy using parent external id when the parent is not part of the batch being inserted.
- `name` parameter of files.upload_bytes is now required, so as not to raise an exception in the underlying API.
