[DataCatalog2.0]: Draft of AbstractDataCatalog and KedroDataCatalog (work in progress)

Solves #3925, #3926, #3916

Development notes

This PR includes a draft of the following:

1. Implement draft of AbstractDataCatalog and KedroDataCatalog(AbstractDataCatalog)

• AbstractDataCatalog supports instantiation from configuration and/or datasets
• AbstractDataCatalog stores the configuration provided

2. Rework dataset pattern resolution logic:

• Pattern resolution logic moved out from _get_dataset() to resolve_patterns()
• Pattern resolution logic split into actual resolution and updating datasets/configurations
• _dataset_patterns and _default_patterns now obtained from config at the __init__
• Added resolved_ds_configs property to store resolved datasets' configurations at the catalog level
• add() method adds or replaces the dataset and its configuration
• add_feed_dict() renamed to add_from_dict()
• introduces _runtime_patterns catalog field to keep the logic of processing dataset/default/runtime patterns clear
• removed shallow_copy() method used to add extra_dataset_patterns at runtime, replaced it with dedicated - add_runtime_patterns() method

3. Rework dataset access logic

• Removed _FrozenDatasets and access datasets as properties
• Add get dataset by name feature: dedicated function and access by key
• Added iterate over the datasets feature
• We still do not allow to modify dataset property but allow add(replace=True)

4. Make KedroDataCatalog mutable:

• We do not want to make datasets property public not to encourage behaviour when users configure the catalog via modifying the datasets dictionary
• _datasets property remained protected, but public datasets property was added, returning a deep copy of _datasets while the setter is still not allowed; the same is applied to the _resolved_ds_configs property
• One can still extend and replace _datasets via the catalog.add() method

5. To make AbstractDataCatalog compatible with the current runners' implementation several methods - release(), confirm() and exists() were kept as the part of interface. But they only have a meaningful implementation for KedroDataCatalog
