What does this PR do?

This PR:

  • Updates the cipher_suites documentation to better display TLS version compatibility.
  • Adds a tagged region around the content so that it can be reused in APM Server's input (agent ←→ server) documentation. Note that I attempted to list TLS versions for each cipher, but it made the content tougher to scan. I think it works best to only note the ciphers that are compatible with 1.2.
  • Links to Go's crypto library default cipher suites. Is this the correct place to link?

Why is it important?

This content previously only existed in the APM Server's output (server ←→ es) documentation.

Chatted with @andrewvc about adding the following ciphers to the documentation:

beats/libbeat/common/transport/tlscommon/types.go

Lines 69 to 71 in 5f42d21

"TLS-AES-128-GCM-SHA256": tlsCipherSuite(tls.TLS_AES_128_GCM_SHA256),
"TLS-AES-256-GCM-SHA384": tlsCipherSuite(tls.TLS_AES_256_GCM_SHA384),
"TLS-CHACHA20-POLY1305-SHA256": tlsCipherSuite(tls.TLS_CHACHA20_POLY1305_SHA256),

We agreed they should be added, but now I'm noticing that TLS 1.3 cipher suites are not individually configurable in Go... So I don't think they need to be added after all.

Bump @elastic/integrations-services. Can I get a review on this, please? I'm specifically interested in the two open questions in the description.

@bmorelli25 I added the cipher suites there not so much to make them configurable but so that inverse lookups would work (we flip that map around and use it for inverse lookups). We use these inverse lookups to report the cipher suite used in heartbeat data. If they aren't configurable maybe the docs should reflect that, but the code should stay.

Neat. The docs say "Note that TLS 1.3 cipher suites are not individually configurable in Go, so they are not included in this list.", so I think we're good then! Thanks, Andrew.

EDIT: Sorry, I reread and realize I wasn't clear in my comment above. I wasn't suggesting we remove them from the code, just that we exclude them from the docs.
