* Initialized basic outline of TOTP backend using Postgresql backend as template * Updated TOTP backend.go's structure and help string * Updated TOTP path_roles.go's structure and help strings * Updated TOTP path_role_create.go's structure and help strings * Fixed typo in path_roles.go * Fixed errors in path_role_create.go and path_roles.go * Added TOTP secret backend information to cli commands * Fixed build errors in path_roles.go and path_role_create.go * Changed field values of period and digits from uint to int, added uint conversion of period when generating passwords * Initialized TOTP test file based on structure of postgresql test file * Added enforcement of input values * Added otp library to vendor folder * Added test steps and cleaned up errors * Modified read credential test step, not working yet * Use of vendored package not allowed - Test error * Removed vendor files for TOTP library * Revert "Removed vendor files for TOTP library" This reverts commit fcd030994bc1741dbf490f3995944e091b11da61. * Hopefully fixed vendor folder issue with TOTP Library * Added additional tests for TOTP backend * Cleaned up comments in TOTP backend_test.go * Added default values of period, algorithm and digits to field schema * Changed account_name and issuer fields to optional * Removed MD5 as a hash algorithm option * Implemented requested pull request changes * Added ability to validate TOTP codes * Added ability to have a key generated * Added skew, qr size and key size parameters * Reset vendor.json prior to merge * Readded otp and barcode libraries to vendor.json * Modified help strings for path_role_create.go * Fixed test issue in testAccStepReadRole * Cleaned up error formatting, variable names and path names. Also added some additional documentation * Moveed barcode and url output to key creation function and did some additional cleanup based on requested changes * Added ability to pass in TOTP urls * Added additional tests for TOTP server functions * Removed unused QRSize, URL and Generate members of keyEntry struct * Removed unnecessary urlstring variable from pathKeyCreate * Added website documentation for TOTP secret backend * Added errors if generate is true and url or key is passed, removed logger from backend, and revised parameter documentation. * Updated website documentation and added QR example * Added exported variable and ability to disable QR generation, cleaned up error reporting, changed default skew value, updated documentation and added additional tests * Updated API documentation to inlude to exported variable and qr size option * Cleaned up return statements in path_code, added error handling while validating codes and clarified documentation for generate parameters in path_keys
