Kirill Bulatov 2759f1a22e Evict layers on demand (#3486) ...

Closes https://github.com/neondatabase/neon/issues/3439

Adds a set of commands to manipulate the layer map:
* dump the layer map contents
* evict the layer form the layer map (remove the local file, put the
remote layer instead in the layer map)
* download the layer (operation, reversing the eviction)

The commands will change later, when the statistics is added on top, so
the swagger schema is not adjusted.

The commands might have issues with big amount of layers: no pagination
is done for the dump command, eviction and download commands look for
the layer to evict/download by iterating all layers sequentially and
comparing the layer names.
For now, that seems to be tolerable ("big" number of layers is ~2_000)
and further experiments are needed.
