Currently the mutation compactor supports v1 and v2 output and has a v1
output. The next step is to add a v2 output but this would lead to a
full conversion matrix which we want to avoid. So in preparation we drop
the v1 input support. Most inputs were already v2, but there were some
notable exceptions: tests, the compacting reader and the multishard
query code. The former two was a simple mechanical update but the latter
required some further work because it turned out the v2 version of
evictable reader wasn't used yet and thus it managed to hide some bugs
and dropped features. While at it, we migrate all evictable and
multishard reader users to the v2 variant of the respective readers and
drop the v1 variant completely.
With this the road is open to a v2 compactor output and therefore to a
v2 sstable writer.
Tests: unit(dev, release), dtest(paging_additional_test.py)
