Base / Common class properties/types

Class types are created individually, even though they share a lot of common properties.

Eg:

export class RPMRepositoryType {
  autopublish?: boolean;
  checksum_type?: 'sha1' | 'sha256' | 'sha512';
  description: string | null;
  gpgcheck?: 0 | 1 | 2;
  latest_version_href?: string;
  metadata_signing_service?: string;
  name: string;
  pulp_created?: string;
  pulp_href?: string;
  pulp_labels: Record<string, string>;
  pulp_last_updated?: string;
  remote: string | null;
  repoclosure_verification?: boolean;
  repo_gpgcheck?: 0 | 1;
  retain_package_versions?: number;
  retain_repo_versions: number | null;
  versions_href?: string;
}

export class FileRepositoryType {
  autopublish?: boolean;
  description: string | null;
  latest_version_href?: string;
  manifest?: string;
  name: string;
  prn?: string;
  pulp_created?: string;
  pulp_href?: string;
  pulp_labels: Record<string, string>;
  pulp_last_updated?: string;
  remote: string | null;
  retain_repo_versions: number;
  versions_href?: string;
}

A parent class type for each pulp base type (remote, content, repository, distribution, publication), could be created to remove the duplication between these classes.

No files, tests, or entry points are named. Locate the RPMRepositoryType and FileRepositoryType definitions, then review the other remote, content, repository, distribution, and publication types for repeated properties. Done means shared parent types remove the duplication while preserving the existing property types.
