This moves the rollup cleanup code for http tests from the high level rest
client into the test framework and then entirely removes the rollup cleanup
code for http tests that lived in x-pack. This is nice because it
consolidates the cleanup into one spot, automatically invokes the cleanup
without the test having to know that it is "about rollup", and should allow
us to run the rollup docs tests.
Part of #34530
Our rest testing framework has support for sniffing the host metadata on
startup and, before this change, it'd sniff that metadata before running
the first test. This prevents running these tests against
elasticsearch installations that won't support sniffing like Elastic
Cloud. This change allows tests to only sniff for metadata when they
encounter a test with a `node_selector`. These selectors are the things
that need the metadata anyway and they are super rare. Tests that use
these won't be able to run against installations that don't support
sniffing but we can just skip them. In the case of Elastic Cloud, these
tests were never going to work against Elastic Cloud anyway.
Proper cleanup of the docs snippet tests depends on detecting what is being tested (ML, Watcher, etc) this is deduced from the file path and so we must account for Windows and Unix path separators
We have made node selectors configurable per request, but all
of other language clients don't allow for that.
A good reason not to do so, is that having a different node selector
per request breaks round-robin. This commit makes NodeSelector
configurable only at client initialization. It also improves the docs
on this matter, important given that a single node selector can still
affect round-robin.
This commit exposes the master version to the REST test context. This
will be needed in a follow-up where the master version will be used to
determine whether or not a certain warning header is expected.
