Empty "create data view" and welcome screen broken when ent search is enabled

[Dosant]

Kibana version: 8.0.x, partially 8.1.0

Describe the bug:

Welcome screen and "Create data view" empty state don't work because of logs-enterprise_search.api-default that is created by default with enterprise search

Because #82851 is fixed in 8.1, the existing workaround with FLEET_ASSETS_TO_IGNORE no longer needed for welcome screen. This makes welcome screen only broken in 8.0.x, but working in 8.1.0.

However logs-enterprise_search.api-default slightly breaks the empty state of "create data view" screen where it says, that "you have data, now create data view" instead of "you don't have any data".

Short term we want to add logs-enterprise_search.api-default to existing ignore list

kibana/src/plugins/data_views/server/has_user_index_pattern.ts

Lines 18 to 62 in 6627bd8

	export const hasUserIndexPattern = async ({ esClient, soClient }: Deps): Promise<boolean> => {
	const indexPatterns = await soClient.find<IndexPatternSavedObjectAttrs>({
	type: 'index-pattern',
	fields: ['title'],
	search: `*`,
	searchFields: ['title'],
	perPage: 100,
	});
	if (indexPatterns.total === 0) {
	return false;
	}
	// If there are any index patterns that are not the default metrics-* and logs-* ones created by Fleet,
	// assume there are user created index patterns
	if (
	indexPatterns.saved_objects.some(
	(ip) =>
	ip.attributes.title !== FLEET_ASSETS_TO_IGNORE.METRICS_INDEX_PATTERN &&
	ip.attributes.title !== FLEET_ASSETS_TO_IGNORE.LOGS_INDEX_PATTERN
	)
	) {
	return true;
	}
	const resolveResponse = await esClient.indices.resolveIndex({
	name: `${FLEET_ASSETS_TO_IGNORE.LOGS_INDEX_PATTERN},${FLEET_ASSETS_TO_IGNORE.METRICS_INDEX_PATTERN}`,
	});
	const hasAnyNonDefaultFleetIndices = resolveResponse.indices.some(
	(ds) => ds.name !== FLEET_ASSETS_TO_IGNORE.METRICS_ENDPOINT_INDEX_TO_IGNORE
	);
	if (hasAnyNonDefaultFleetIndices) return true;
	const hasAnyNonDefaultFleetDataStreams = resolveResponse.data_streams.some(
	(ds) =>
	ds.name !== FLEET_ASSETS_TO_IGNORE.METRICS_DATA_STREAM_TO_IGNORE &&
	ds.name !== FLEET_ASSETS_TO_IGNORE.LOGS_DATA_STREAM_TO_IGNORE
	);
	if (hasAnyNonDefaultFleetDataStreams) return true;
	return false;
	};

Longer term we should come up with a strategy of handling empty states.
