Hide constructors of utility classes

[vil02]

Bug report for Cloudinary Java SDK

Before proceeding, please update to latest version and test if the issue persists

Describe the bug in a sentence or two.

These classes:

• ApiUtils,
• SmartUrlEncoder,
• Util,
• HtmlEscape,
• StringUtils,
• ObjectUtils,
• Base64Map,
• Feature,
• MetadataTestHelper,
• Singleton,

are utilities and their constructors should be hidden and they should be marked as final. Such change makes it harder to misuse them (prevents instantiation and inheritance) and makes the coverage reports more accurate.

Issue Type (Can be multiple)

[ ] Build - Can’t install or import the SDK [ ] Performance - Performance issues [ ] Behaviour - Functions aren’t working as expected (Such as generate URL) [ ] Documentation - Inconsistency between the docs and behaviour [x] Other (Specify) - code quality
