New endpoints

[charlottekostelic]

Added methods for new endpoints:

• Methods with new functionality:
  • create_bib
  • get_bib_classification
  • get_bib_holdings
  • get_institution_holding_codes
  • match_bib
  • replace_bib
  • set_holding (sets a holding with MARC record)
  • unset_holding (unsets a holding with MARC record)
  • validate_bib
• Methods for endpoints that correspond to previous functionality (old_method -> new_method)
  • search_current_control_numbers -> get_current_oclc_numbers
  • holding_get_status -> get_institution_holdings
  • search_general_holdings -> search_bib_holdings
  • search_brief_bib_other_editions -> search_brief_bibs_other_editions
  • holding_set -> set_holding_oclc_number
  • holding_unset -> unset_holding_oclc_number

Added W503 (line break before binary operator) to flake8 per-file-ignores for tests

Changed existing methods based on new endpoints and parameters:

• search_brief_bibs: added new args
• search_shared_print_holdings: removed offset and limit from args based on change to endpoint
• get_full_bib: changed options for responseFormats based on change to endpoint

Changed args for MetadataSession methods to camelCase

Removed handling of 409 error from Query class

I'm going to close this and break it into smaller PRs.
