Rule S2068: support url userinfo component

The URL user info component can contain a hard-coded password:

• Go

  url1 := "scheme://user:azerty123@domain.com" // Sensitive
  url2 := "scheme://user:@domain.com"           // Compliant
  url3 := "scheme://user@domain.com:80"         // Compliant
  url4 := "scheme://user@domain.com"            // Compliant
  url5 := "scheme://domain.com/user:azerty123"  // Compliant
  

• Ruby

  url1 = "scheme://user:azerty123@domain.com" # Sensitive
  url2 = "scheme://user:@domain.com"           # Compliant
  url3 = "scheme://user@domain.com:80"         # Compliant
  url4 = "scheme://user@domain.com"            # Compliant
  url5 = "scheme://domain.com/user:azerty123"  # Compliant
  

• Apex

  String url1 = 'scheme://user:azerty123@domain.com'; // Sensitive
  String url2 = 'scheme://user:@domain.com'; // Compliant
  String url3 = 'scheme://user@domain.com:80'; // Compliant
  String url4 = 'scheme://user@domain.com'; // Compliant
  String url5 = 'scheme://domain.com/user:azerty123'; // Compliant
  

• Kotlin

  val url1 = "scheme://user:azerty123@domain.com" // Sensitive
  val url2 = "scheme://user:@domain.com"           // Compliant
  val url3 = "scheme://user@domain.com:80"         // Compliant
  val url4 = "scheme://user@domain.com"            // Compliant
  val url5 = "scheme://domain.com/user:azerty123"  // Compliant
  

• Scala

  val url = "scheme://user:azerty123@domain.com" // Sensitive
  val url = "scheme://user:@domain.com"           // Compliant
  val url = "scheme://user@domain.com:80"         // Compliant
  val url = "scheme://user@domain.com"            // Compliant
  val url = "scheme://domain.com/user:azerty123"  // Compliant
  

Exception: no issue should be raised if user and password part of the userinfo component are the same:

• Kotlin

  val url1 = "scheme://admin:admin@domain.com" // Compliant
