Provide a cleaner way to disable inline comments

[gubenkoved]

As of now in order to suppress "#" interpretation as inline comment we need to use _inspec=True which is really obscure.

This behaviour is documented https://configobj.readthedocs.io/en/latest/configobj.html, however it is still quite clumsy and not clear on the suer code level.

As of ConfigObj 4.3.0 you can also pass in a ConfigObj instance as your configspec. This is especially useful if you need to specify the encoding of your configspec file. When you read your configspec file, you must specify list_values=False. If you need to support hashes inside the configspec values then you must also pass in _inspec=True. This is because configspec files actually use a different syntax to config files and inline comment support must be switched off to correctly read configspec files with hashes in the values.

I suggest to add an explicit way to suppress this behaviour. For example: disable_inline_comments=True.

inline_comment_prefixes, default value: None
Comment prefixes are strings that indicate the start of a valid comment within a config file. comment_prefixes are used only on otherwise empty lines (optionally indented) whereas inline_comment_prefixes can be used after every valid value (e.g. section names, options and empty lines as well). By default inline comments are disabled and '#' and ';' are used as prefixes for whole line comments.
