ASM API Update - Add subdomain endpoints

[ghost]

This changeset adds access additional subdomain endpoints:

Underneath the main api:

• /v1/assets/domains/:domain/subdomains/:subdomain
  • GET: read subdomain details
  • /comments (POST: create comment, GET: list comments)
  • /comments/:commentId (GET: get single comment|DELETE: delete single comment)
  • /tags (POST: create tag)
  • /tags/:tagId (DELETE: delete single tag)

These are done by obtaining an instance representing the top-level domain that you will manipulate subdomains for:

client = AsmClient()

subdomains = client.get_subdomains("my_domain.com")

details_object = subdomains.get_asset_by_id("sub.my_domain.com")

subdomains.add_tag("sub.my_domain.com", "new tag")
subdomains.delete_tag("sub.my_domain.com", "new tag")

comments_page = subdomains.get_comments("sub.my_domain.com")
subdomains.add_comment("sub.my_domain.com", "new comment")
subdomains.delete_comment("sub.my_domain.com", "new comment")
subdomains.get_comment_by_id("sub.my_domain.com", 3)

Hey @thomas-censysio could I ask you to rebase from main? I fixed the CI config to work for external PRs.
