Pass structure warnings to verification reports

[novotnyr]

Pass structure warnings and structure unacceptable warnings to the verification reports.

This will show warnings in all outputs (HTML, Markdown, stdout).

For example:

Plugin com.github.novotnyr.plugin-service-preloading:1.0-SNAPSHOT against IE-203.7717.75: Compatible. 2 plugin configuration defects
Plugin structure warnings (2): 
    Invalid plugin descriptor 'plugin.xml'. The change-notes parameter contains the default value 'Add change notes here' or 'most HTML tags may be used'.
    Service preloading is deprecated in the <com.intellij.applicationService> element. Remove the 'preload' attribute and migrate to listeners, see https://plugins.jetbrains.com/docs/intellij/plugin-listeners.html.
Dynamic Plugin Eligibility:
    Plugin can probably be enabled or disabled without IDE restart

See MP-6458 Structure Warnings are not reported in CLI outputs

• Make default IntelliJ plugin implementation carry structural problems
• Improve presentation of plugin defects in the HTML output
• Plugin Detail Provider will resolve available plugin problems from plugin implementation
• Remove unused methods from Plugin Detail Provider which handle plugin problems in a manual way

Are there no tests that need alignment? Can we create them?
