Remote cluster stats API currently only returns useful information if the strategy in use is the SNIFF mode. This PR modifies the API to provide relevant information if the user is in the SIMPLE mode. This information is the configured addresses, max socket connections, and open socket connections.
Currently an intermediate proxy must route conncctions to the appropriate remote cluster when using simple mode. This commit offers a additional mechanism for the proxy to route the connections by including the hostname in the TLS SNI header.
This commit renames the simple connection mode to the proxy connection mode for remote cluster connections. In order to do this, the mode specific settings which we namespaced by their mode (ex: sniff.seed and proxy.addresses) have been reverted.
Currently, the remote proxy connection mode uses a list setting for the proxy address. This commit modifies this so that the setting is proxy_address and only supports a single remote proxy address.

Update remote cluster stats to support simple mode (#49981
Remote cluster stats API currently only returns useful information if
the strategy in use is the SNIFF mode. This PR modifies the API to
provide relevant information if the user is in the SIMPLE mode. This
information is the configured addresses, max socket connections, and
open socket connections.
Send hostname in SNI header in simple remote mode (#50247)
Currently an intermediate proxy must route conncctions to the
appropriate remote cluster when using simple mode. This commit offers
a additional mechanism for the proxy to route the connections by
including the hostname in the TLS SNI header.
Rename the remote connection mode simple to proxy (#50291)
This commit renames the simple connection mode to the proxy connection
mode for remote cluster connections. In order to do this, the mode specific
settings which we namespaced by their mode (ex: sniff.seed and
proxy.addresses) have been reverted.
Modify proxy mode to support a single address (#50391)
Currently, the remote proxy connection mode uses a list setting for the
proxy address. This commit modifies this so that the setting is
proxy_address and only supports a single remote proxy address.
