Subject: [PATCH] test: enable parallel mode for wal_off tests
- Box configuration parameter `memtx_memory` is increased, because the
test `lua` after `tuple` failed with the error:
`Failed to allocate 368569 bytes in slab allocator for memtx_tuple`
despite `collectgarbage('collect')` calls after cases with huge/many
tuples.
The statistics before the allocation fail gives the following values:
```
box.slab.info()
---
- items_size: 72786472
items_used_ratio: 4.43%
quota_size: 107374592
quota_used_ratio: 93.75%
arena_used_ratio: 6.1%
items_used: 3222376
quota_used: 100663296
arena_size: 100663296
arena_used: 6105960
```
The reason of the fail seems to be a slab memory fragmentation. It is
not clear for now whether we should consider this as a tarantool
issue.
- Test `snapshot_stress` counts snapshot files present in the
working directory and can reach the default 'checkpoint_count' value
`2` if a previous test write its snapshots before.
- Restarting the default server w/o cleaning a working directory
can leave a snapshot that holds a state saved at the middle of a test,
before dropping of the space 'tweedledum' (because WAL is disabled),
that can cause the error `Space 'tweedledum' already exists` for a
following test.
- Use unix sockets because of errors `Address already in use`.
Part of #2436
