Reserved project and group names

To not conflict with existing routes used by GitLab, some words cannot be used as project or group names. These words are listed in the path_regex.rb file, where:

• TOP_LEVEL_ROUTES are names reserved as usernames or top-level groups.
• PROJECT_WILDCARD_ROUTES are names reserved for subgroups or projects.
• GROUP_ROUTES are names reserved for all groups or projects.

Rules for usernames, project and group names, and slugs

• Usernames must start and end with a letter (a-zA-Z) or a digit (0-9). Additionally:
  • Usernames and group names can contain only letters (a-zA-Z), digits (0-9), emoji, underscores (_), dots (.), parentheses (()), dashes (-), or spaces.
  • Project names can contain only letters (a-zA-Z), digits (0-9), emoji, underscores (_), dots (.), pluses (+), dashes (-), or spaces.
• Usernames and project or group slugs:
  • Must start and end with a letter (a-zA-Z) or digit (0-9).
  • Must not contain consecutive special characters.
  • Cannot end in .git or .atom.
