Disable clang-format from super-linter

Disable clang-format from super-linter

To see how this works and the amounts of seemingly unconfigurable issues that appear:

1. Install using pip. This installs a newer 14 version.

2. Dump the current configuration to get all (?) the configuration options:

   clang-format -style=llvm -dump-config > current_clang-format
   

3. See configuration options.

4. To emulate the super-linter behavior, run:

   clang-format --dry-run -Werror chapters/data/lab/support/alloc-size/alloc_size.c
   

There are -Wclang-format-violation warnings that we weren't able to get rid of. We didn't find the configuration options. Some situations:

• Having a Tab between the name of a macro and its value. clang-format requires to use a certain number of space. We didn't find any option to configure the use of tabs.
• clang-format is strict to the use of spaces around arithmetic operators. For example, using int a = b-1; triggers a warning / error to have it written as int a = b - 1;. This seems a bit too much and should be configurable. But again, we didn't find an option to disable this.

A rather complete configuration file is the one used by cpp_weekly.

1. You made this branch from Data_lab, so you carried over the changes to the data lab to this PR.
2. Isn't this too drastic? I know our coding style isn't too compatible with the clang standard, but are they that different that it requires disabling clang-format altogether?

1. Fixed.
2. See my update to the PR message.

Given the additional details you provided, I now believe you're right to remove clang-format. cpplint should suffice for basic errors such as trailing whitespaces.
