Migrate migration docs from 6.0 to 7.0 (#26227) * Migrate migration docs from 6.0 to 7.0 Since we only keep one version of migration docs and master is now on 7.0, we should migrate these so breaking changes can be added in the right place. * Remove release notes as well They link to the migration guides, so they have to go. * Add placeholder notes for 7.0 so doc build is happy

Packaging: Unmark systemd service file as a config file (#29004) Systemd overrides should happen through /etc/systemd/system, not directly editing the service file. This commit removes marking the service file as configuration for rpm and deb packages.

Remove azure deprecated settings (#26099) Follow up for #23405. We remove azure deprecated settings in 7.0: * The legacy azure settings which where starting with `cloud.azure.storage.` prefix have been removed. This includes `account`, `key`, `default` and `timeout`. You need to use settings which are starting with `azure.client.` prefix instead. * Global timeout setting `cloud.azure.storage.timeout` has been removed. You must set it per azure client instead. Like `azure.client.default.timeout: 10s` for example.

Replace `delimited_payload_filter` by `delimited_payload` (#26625) The `delimited_payload_filter` is renamed to `delimited_payload`, the old name is deprecated and should be replaced by `delimited_payload`. Closes #21978

Scripting: Remove getDate methods from ScriptDocValues (#30690) The getDate() and getDates() existed prior to 5.x on long fields in scripting. In 5.x, a new Date type for ScriptDocValues was added. The getDate() and getDates() methods were left on long fields and added to date fields to ease the transition. This commit removes those methods for 7.0.

LLREST: Drop deprecated methods (#33223) In #29623 we added `Request` object flavored requests to the low level REST client and in #30315 we deprecated the old `performRequest`s. In a long series of PRs I've changed all of the old style requests. This drops the deprecated methods and will be released with 7.0.

Elasticsearch support to JSON logging (#36833) In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine. To populate additional fields node.id and cluster.uuid which are not available at start time, a cluster state update will have to be received and the values passed to log4j pattern converter. A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter. Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace see ESJsonLayout.java for more details and field descriptions Docker log4j2 configuration is now almost the same as the one use for ES binary. The only difference is that docker is using console appenders, whereas ES is using file appenders. relates: #32850

Elasticsearch 7.0 can read indices created in version 6.0 or above. An
Elasticsearch 7.0 node will not start in the presence of indices created in a
version of Elasticsearch before 6.0.
[IMPORTANT]
.Reindex indices from Elasticsearch 5.x or before
=========================================
Indices created in Elasticsearch 5.x or before will need to be reindexed with
Elasticsearch 6.x in order to be readable by Elasticsearch 7.x.
