Include the changes from 0b7511b4 (stack/erp5: expose random_activity_priority
argument of testrunner, 2021-11-22) to customized profiles from slapos
master

By setting this in the test suite configuration, we can force ERP5 tests
to use random priorities for activity processing.

The intended usage is to set this to an empty string, in which case
ERP5's runUnitTest chooses a random value for the seed and prints the
chosen value. It may also be possible to use a value, to reproduce a
previous run.

is not enough.

Anway, given how SST files are written, fallocate
is unlikely to be useful, even less on SSD.

RocksDB seems to have options to disable at runtime (see env/io_posix.cc)
but I see nothing for that in MariaDB configuration.

Steps to reproduce:

With a Btrfs partition (no specific mkfs option and for example 2GB size)
and following MariaDB configuration:

  [mysqld]
  datadir = /tmp/datadir
  disable-log-bin
  plugin-load = ha_rocksdb
  rocksdb_default_cf_options = compression=kNoCompression;bottommost_compression=kZSTD

execute the following queries with `mysql -uroot`:

> USE test;
> CREATE TABLE t(x MEDIUMBLOB) ENGINE=RocksDB;
> INSERT INTO t VALUES(repeat('.',16777215));
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;

Disk usage can be checked with:

> SHOW ENGINE RocksDB STATUS \G

  L2      1/0   288.00 MB ...
 Sum      2/0   432.00 MB ...

and this can be compacted as follows:

> SET GLOBAL rocksdb_compact_cf='default';

> SHOW ENGINE RocksDB STATUS \G

Now using `compsize` (on Debian, it's provided by btrfs-compsize package):

# with -DWITH_FALLOCATE=NO

$ compsize /tmp/datadir/#rocksdb/000029.sst

* Note from @jerome: We have a useless dependency to
 https://pypi.org/project/alabaster/, a sphynx theme,
 but with oic v0.15.1 it's listed as a dependency
 ( https://github.com/OpenIDC/pyoidc/blob/v0.15.1/setup.py#L89 )
 so we don't have a choice. It was fixed later
 ( https://github.com/OpenIDC/pyoidc/issues/598 )
 but after python2 support was dropped.

Fixes 50f6a557 (component/trafficserver: build Lua plugin., 2021-11-23)
LuaJIT has to be build as shared to be referenced by trafficserver
component, because the later is already build as shared.
Also fix a missing rpath

Fixes dbd19730

The caucase binary have to be explicitly provided.

This fixes commit 79ccddeb

JSON schema uses simple string and internal process, and caddy instances are
not kept simple and are not considered future-proof.

This software can use system gcc. On test nodes we observed successful
builds when system gcc is 8.3.0 and failures with system gcc is 6.3.0:

There was missing updates in the test itself.

kvm-exporter supported only disk-type=virtio, as qemuqmpclient.driveBackup
source_drive defaults to virtio0.

For disk-type=ide the source_drive found to be ide0-hd0 by query-block during
runtime, and as it's used, now such disk type is supported.

Without a shebang, supervisord refuses to run the script with the
following error:

supervisor: couldn't exec /srv/slapgrid/slappart8/etc/prerm/slapos_wipe_device_disk: ENOEXEC
supervisor: child process was not spawned

This is a fixup of 0983f1ca

Caucase binaries are required for some testing scenarios.

cls.computer_partition_root_path is filled in by super.setUpClass.
