Description of changes
Create a single connection pool per request to avoid using too much connections of the dial core.
To do this, DialApiClient is created within the RequestContext to store the aiohttp.ClientSession to use for the requests to the dial core. This session accepts only dial relative urls and already has necessary api-key headers.
Metadata url in the AttachmentLink is now represented as a relative url to be able to use it in the DialApiClient session.
