Configurability of analyzer versions

The modification can be used to validate the version of each analyzer. The user can specify all desired analyzers after the --analyzers flag, as was possible before. Also, the exact version number can be typed for each analyzer, separated by an '==' char. For example: 'CodeChecker analyze compile_commands.json -o reports --analyzers clangsa==14.0.0 cppcheck==2.7'. If the version number was not the same as in the current environment, error message would be logged and the system exit would trigger. The user can enumerate the analyzers with or without versions, for example: 'CodeChecker analyze compile_commands.json -o reports --analyzers clangsa=14.0.0 cppcheck'.
