[Library | new-theme]: Allow also ?pid url parameter in datasource landing | Fixes in newSearchPage for service filters.

1. dataProvider.component.ts: [Bug fix] Allow also ?pid url parameter, query accordingly and set canonicalUrl to use it in seoService and scema2jsonld.
2. dataProvider.component.html: Set canonicalUrl into URL of <schema2jsonld> | Use <landing-header> instead of <showTitle>.
3. dataProvider.service.ts: Set url for querying a datasource by pid (if ?pid in landing url param) and parse also the whole record, the objIdentifier and the relcanId.
4. landing-header.component.ts: Added @Input() isSticky: boolean = false; to set less margins when sticky.
5. resultLanding.component.html: Use <landing-header> instead of <showTitle>.
6. resultLanding.component.ts: Use renamed Identifier.getResultPIDFromIdentifiers --> Identifier.getPIDFromIdentifiers.
7. metrics.service.ts: Removed console.log.
8. searchDataproviders.service.ts: Added parsing for relcanId.
9. dataProviderInfo.ts: Added relcanId, objIdentifier, record.
10. result-preview.component.ts: Use renamed Identifier.getResultPIDFromIdentifiers --> Identifier.getPIDFromIdentifiers.
11. string-utils.class.ts: Renamed Identifier.getResultPIDFromIdentifiers --> Identifier.getPIDFromIdentifiers.
12. [SITEMAPS] extractUrlsFromSearch.ts: Use renamed Identifier.getResultPIDFromIdentifiers --> Identifier.getPIDFromIdentifiers.
13. newSearchPage.component.ts: [Bug fix]
   a. entityType for datasources is "dataprovider".
   b. Added service filter options only when entityType == "service".
