Timeouts defaulted to `db::no_timeout` are dangerous. They allow any
modifications to the code to drop timeouts and introduce a source of
unbounded request queue to the system.
This series removes the last such default timeouts from the code. No
problems were found, only test code had to be updated.

* 'no-default-timeouts/v1' of https://github.com/denesb/scylla:
database: database::query*(), database::apply*(): remove default timeouts
database: table::query(): remove default timeout
mutation_query: data_query(): remove default timeout
mutation_query: mutation_query(): remove default timeout
multishard_mutation_query: query_mutations_on_all_shards(): remove default timeout
reader_concurrency_semaphore: wait_admission(): remove default timeout
utils/logallog: run_when_memory_available(): remove default timeout
If the reversing requires more memory than the limit, the read is
aborted. All users are updated to get a meaningful limit, from the
respective table object, with the exception of tests of course.
The former was never really more than a reader_permit with one
additional method. Currently using it doesn't even save one from any
includes. Now that readers will be using reader_permit we would have to
pass down both to mutation_source. Instead get rid of
reader_resource_tracker and just use reader_permit. Instead of making it
a last and optional parameter that is easy to ignore, make it a
first class parameter, right after schema, to signify that permits are
now a prominent part of the reader API.
This -- mostly mechanical -- patch essentially refactors mutation_source
to ask for the reader_permit instead of reader_resource_tracking and
updates all usage sites.
1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
