add support for namespace search-attributes

[Dariusch]

What was changed

I am adding support for adding search attributes while creating a namespace.

Why?

We recently migrated to the temporal chart and missed the option to include the previously used config.

1. How was this tested:

values:

server:
  config:
    namespaces:
      # Enable this to create namespaces
      create: true
      namespace:
        - name: default
          retention: 3d
          searchAttributes: []
        - name: non-default
          retention: 3d
          searchAttributes:
            - name: my_keyword
              type: Keyword
            - name: my_keyword2
              type: Keyword

output:

          command: ['/bin/sh','-c']
          args: ['temporal operator namespace describe -n default || temporal operator namespace create -n default --retention 3d']

Search attributes do not belong to namespaces on self-hosted Temporal.

I'm happy to include this feature, but it needs to be separated from any namespace related code.

[Dariusch]

What do you mean?

Afaik according to the docs they are namespace scoped.

I would be happy to change the PR if you could point me in the right direction.

@Dariusch You are right. Commands to add custom attributes per namespace were introduced in v1.25 (we use it in our project). If you are using Postgres be aware, this functionality is bugged for now.

[robholland]

My apologies, this has changed since I last used it. They are indeed scoped to namespaces. One small change needed though.

[robholland]

Also now learned that Elasticsearch implementation does not have per namespace search attributes, only SQL does. How do you think best to handle that?

[Dariusch]

@robholland I added a condition, comment, and tests only to render the search attributes for the SQL driver
