Closes #17122

Adds a new [server] setting `serve_from_sub_path`. By enabling 
this setting and using a subpath in `root_url` setting, e.g.
`root_url = http://localhost:3000/grafana`, Grafana will be accessible 
on `http://localhost:3000/grafana`. By default it is set to `false` 
for compatibility reasons.

Closes #16623

With the previous configuration `docker-compose build` was always failing.
This moves the dockerfiles in the parent dir and changes paths as a result.

closes #17196

Fixes #14933

* Move log's typings into grafana/ui
* Update the way context is retrieved for Loki

Major changes:

1. getLogRowContext expects row to be of LogRowModel type
2. getLogRowContext accepts generic options object, specific to a datasource of interest. limit option has been removed, and now it's a part of Loki's context query options (see below)
3. LogRowContextProvider performs two queries now. Before, it was Loki ds that performed queries in both directions when getLogRowContext.
4. Loki's getLogRowContext accepts options object of a type:

interface LokiContextQueryOptions {
    direction?: 'BACKWARD' | 'FORWARD';
    limit?: number;
}

This will enable querying in either direction independently and also slightly simplifies the way query errors are handled.

LogRowContextProvider maps the results to a Loki specific context types, basically string[][], as raw log lines are displayed in first version.

Use of singular and added an article for consistency with other titles.
