• Integration seed node validation into form validation

@sebelga @yaronp68 @bleskes I also added a "Auto-follow patterns" subtitle to the CCR app. What do you think?

@cjcenizal ❤️

@cjcenizal Great! Very similar to the first screen I had 😄 What about the empty prompt screen?

[sebelga]

LGTM! Just a text translation is missing.

[sebelga]

The i18n translation is missing ^

[cjcenizal]

Very similar to the first screen I had

Yes, it is. 😄

I tried adding the subtitle to the empty prompt but it seemed a bit cumbersome. I couldn't get the sizing right. I think the message is still clear without it though:

For the Add remote cluster page

Name
A unique name for the remote cluster.

Seed nodes for cluster discovery
The nodes to query to get the cluster state from the remote cluster. Specify multiple seeds so discovery doesn't fail if a node is unavailable.

Make remote cluster optional
By default, a request fails if any of the specified remote clusters are unavailable. To continue processing requests if this cluster is disconnected, enable Skip if unavailable. Learn more.

Toggle switch: Skip if unavailable

Error message: Fix errors before continuing.

Validation message for Seed nodes
A port is required.
At least one seed node is required.

Hint text underneath Seed nodes field:
An IP address or host name, followed by the port.

Placeholder text in Seed nodes field:
host:port

For the Cross Cluster Replication empty state

Title: Automatically follow remote indices

Text: Use an auto-follow pattern to identify the indices that you want to replicate from a remote cluster.

Button label: Create auto-follow pattern

Thanks @gchaps! I made some very slight tweaks to your copy. For the title of the empty state, I had to leave it as-is to maintain parity with the title of this page once an auto-follow pattern has been created.
