Persist '# pragma: allowlist nextline secret' in IniFileParser For ConfigFileTransformers

[jpdakran]

Problem

• # pragma: allowlist nextline secret are not filtered out and secrets on the proceeding line are alerted on
• This is an issue with the ConfigFileTransformer which leverages the IniFileParser
• The transformer and the parser does not track comments in files - This is why our logic is alerting on the secrets which should be whitelisted

Solution

• When parsing files in the IniFileParser persist comments that match the allowlist_nextline_secret comment
• We do not want to keep all comments and we do not want to keep allowlist_secret comment (Which occur on the same line as a secret) since this is working properly
