Analyze all files under a directory

[dkrupp]

Is your feature request related to a problem? Please describe. I would like to analyze all files under a directory (a module).

CodeChecker analyze invocation supports individual files, but not directories or file glob patterns e..g.

CodeChecker analyze ./src/module/* should analyze all files directly under the module directory.

while

CodeChecker analyze ./src/module/** should analyze all files under the directory recursively.

relative and absolute paths should be supported.
