• typescript-estree: switch to globby (#2418) (3a7ec9b), closes #2398

BREAKING CHANGES

• typescript-estree: - removes the ability to supply a RegExp to projectFolderIgnoreList, and changes the meaning of the string value from a regex to a glob.
• • Removed decorators property from several Nodes that could never semantically have them (FunctionDeclaration, TSEnumDeclaration, and TSInterfaceDeclaration)

• Removed AST_NODE_TYPES.Import. This is a minor breaking change as the node type that used this was removed ages ago.
