[stable-2.5] Backport test infra updates and test fixes. (#49204)

* Switch tests from RHEL 7.5 to 7.6.

(cherry picked from commit 6745ee7cc8)

* Remove CI platform: freebsd/10.4

(cherry picked from commit e6ffc4f89a)

* Add `--raw` option to ansible-test shell command.

It is currently supported only with the `--remote` option.

This makes it easier to troubleshoot new instances which are not
yet supported by the setup scripts used by ansible-test.

(cherry picked from commit 0826a00803)

* Support skip of platforms by version in tests. (#48826)

* Support skip of platforms by version in tests.

Previously a remote platform could be skipped completely using the alias:

`skip/{platform}` such as `skip/rhel`

Now a specific platform version can be skipped using the alias:

`skip/{platform}{version}` such as `skip/rhel7.6`

This feature is available for platforms specified with the `--remote` option.

* Add skip by version to the docs.

(cherry picked from commit 8066acc90c)

* Fix ansible-test skip warning message.

(cherry picked from commit 3b705efc93)

* Fix lookup_passwordstore test skipping. (#49178)

* Fix lookup_passwordstore test skipping.

Skip all of RHEL instead of specific versions.
Skip all of CentOS < 7 instead of specific versions.

This makes the test more robust when testing newer versions.

Tests could be executed on RHEL if EPEL was installed during the test.
(cherry picked from commit 704dae2cda)
