Automate code formatting using git hooks

[mraduldubey]

Is your feature request related to a problem? Please describe.
We should automate code formatting, which currently is a manual task and leads to extra commits/CI runs

Describe the solution you'd like
Git pre commit hooks to ensure the code is formatted before the commit even happens, so that the git history is completely clean

Describe alternatives you've considered
Server side git hooks

Additional context
we need to integrate clang formatting to do the actual formatting of the code & git hooks will automate it
