Doris support to use Clangd and Clang-Tidy to diagnostic code. Clangd and Clang-Tidy already has in LDB-toolchain，also can install by self.
Clang-Tidy can do some diagnostic config, config file .clang-tidy is in Doris root path. Compared with vscode-cpptools, clangd can provide more powerful and accurate code jumping for vscode, and integrates the analysis and quick-fix functions of clang-tidy.
First we should install clangd plugin, then edit settings.json or just change config on gui. Before using, compile be(RELEASE) and be-ut(ASAN) once to generate the corresponding compile_commands.json file.
