python script clang tidy for reporting

[SajaKhdour]

• New python script to report functions which exceeds recommended size/complexity thresholds [readability-function-size].
• Thresholds: (LineThresholods, BranchThresholds, NestingThresholds)
• to apply this script as a command you need to call the paths of (clang-tidy-report.py) script with (clang-report.txt) that generated before to report it with (.clang-tidy) config. like this:
  python <path-of-clang-tidy-script> <path-of-clang-report.txt> <path-of-.clang-tidy>
• then will show you the final report of these functions

We just talked about this detail via Skype. My notes: please do not hard-code the options here. Instead, cycle over all the check options.

Here's some example I wrote (my last meeting was not so fruitful for me ;-)) for your reference - maybe it helps to make my point clear:

rempler@RT-Z0ITK:~/r/eclipse$ cat kiso/core/.clang-tidy
---
Checks: '-*, readability-*, clang-analyzer-*, misc-*'

CheckOptions:
 - key:          readability-function-size.LineThreshold
   value:        '120'
 - key:          readability-function-size.BranchThreshold
   value:        '15'
 - key:          readability-function-size.NestingThreshold
   value:        '7'
 - key:          readability-function-size.ParameterThreshold
   value:        '8'
 - key:          readability-function-size.StatementThreshold

rempler@RT-Z0ITK:~/r/eclipse$ cat clang_options_extract.py
filne = "kiso/core/.clang-tidy"
with open(filne, 'r+') as f:
    lines = f.readlines()
    for i in range(0, len(lines)):
        line = lines[i]
        # CheckOptions:
        if line[:7] == " - key:":
            valueline = lines[i + 1] # you may want to check that i < len(lines)
            key = line.split(":")[1]
            value = valueline.split(":")[-1:][0]
            print('--> key: ', key.strip())
            print('--> val: ', value.strip())

@elbosch : I don't want to interfere here - I had a quick chat with Saja about her code while we talked about our Kiso daily. I just wanted to give her a hint in code from what I thought about.

@elbosch and @SajaKhdour : after I thought about it a little - maybe I think too complicated? What if we just output the clang-tidy file itself and that's it. No special formatting but the pure text file in our Jenkins dashboard... Just an idea. This could increase our effectivity here.
