The waffle classes previously in future are now available directly from
edx_toggles.toggles. Since this future module is going to be removed soon,
we become future-proof by getting rid of it.
* fix: Correcting logic for xblock_handler token expiration
The previous math had a date math error which resulted in token expiring in 0-2 days
instead of 2-4 days

This includes the following settings:
- BLOCK_STRUCTURES_SETTINGS : setting dictionary which stores the other different block structures related settings
- BLOCK_STRUCTURES_SETTINGS['PRUNING_ACTIVE'] : keeps only a specific number of versions of each block structure, and deletes the rest
- BLOCK_STRUCTURES_SETTINGS['COURSE_PUBLISH_TASK_DELAY'] : specifies the delay, in seconds, after a new edit of a course is published before updating the block structures cache
- BLOCK_STRUCTURES_SETTINGS['TASK_DEFAULT_RETRY_DELAY'] : Specifies the delay, in seconds, between retry attempts for block structure tasks
- BLOCK_STRUCTURES_SETTINGS['TASK_MAX_RETRIES'] : specifies the max number of retries per block structure task
- BLOCK_STRUCTURES_SETTINGS['STORAGE_CLASS'] : specifies the storage which block structures would be saved to when storage backed block structures are enabled
Example: 'storages.backends.s3boto.S3BotoStorage'
- BLOCK_STRUCTURES_SETTINGS['STORAGE_KWARGS'] : specifies additional arguments needed when utilizing storage for storing storage backed block structures
Example: { bucket: 'test-edxapp' }
- BLOCK_STRUCTURES_SETTINGS['DIRECTORY_PREFIX'] : specifies the path to which storage backed block structures are saved
Example: '/courses/'
This also includes the following waffle switches:
- block_structure.storage_backing_for_cache : enables storage backed block structures, used to retrieve the block structures from storage instead of regenerating the structure, when not available in cache
it is important to note that this is important for production because it reduces response times on block structure related apis
- block_structure.raise_error_when_not_found : raises an error if the block structure requested doesnt exist in store or is outdated
- block_structure.invalidate_cache_on_publish : invalidates the block structure cache when courses are published
