Support for tls v1.3 in opensearch-dashboards

[aggarwalShivani]

Description:

(link to original query)
Opensearch supports TLS v1.3 for both http and transport-layer communication.
(Ref - https://github.com/opensearch-project/OpenSearch/blob/0ba0e7cc26060f964fcbf6ee45bae53b3a9941d0/libs/ssl-config/src/main/java/org/opensearch/common/ssl/SslConfiguration.java#L69)

However, opensearch-dashboards also does not support tls 1.3 yet. (Ref -

OpenSearch-Dashboards/src/core/server/http/ssl_config.ts

Line 72 in 9a2d3e6

schema.oneOf([schema.literal('TLSv1'), schema.literal('TLSv1.1'), schema.literal('TLSv1.2')]),

)

Issue: As a result, if opensearch runs with tls 1.3 enabled for http communication, opensearch-dashboard would fail to connect to opensearch and wont start.
Note - In kibana, TLS 1.3 is supported only from 7.11.0 and not available in older versions i.e. 7.10 from which opensearch-dashboards is derived.

This feature is to request support for tls 1.3.

Hi,
Can you help us with the plan for supporting TLS 1.3 on Opensearch-dashboards? There is no update from last 1yr and we're really looking forward to move to TLS 1.3.
