Rename AD to time series analytics & Resolve Compiler Errors (opensea…

…rch-project#951)

This commit focuses on renaming the AnomalyDetectorPlugin to TimeSeriesAnalyticsPlugin as well as addressing compiler errors due to package import changes. The primary transformations are:

* Renamed AnomalyDetectorPlugin to TimeSeriesAnalyticsPlugin.
* Updated all references from AnomalyDetectorPlugin to TimeSeriesAnalyticsPlugin.
* Amended plugin information in build.gradle and src/main/resources/es-plugin.properties.
* Switched job type in TimeSeriesAnalyticsPlugin from opendistro_anomaly_detector to opensearch_time_series_analytics.

These changes led to the modification of our plugin binary from opensearch-anomaly-detection-3.0.0.0-SNAPSHOT.jar to opensearch-time-series-analytics-3.0.0.0-SNAPSHOT.jar.

Moreover, following changes from OpenSearch Pull Request #8157, compiler errors were encountered, which were resolved by updating the import packages

* org.opensearch.common.io.stream.NamedWriteableRegistry => org.opensearch.core.common.io.stream.NamedWriteableRegistry
* org.opensearch.common.xcontent.XContentParserUtils => * org.opensearch.core.xcontent.XContentParserUtils
* org.opensearch.common.bytes.BytesArray => org.opensearch.core.common.bytes.BytesArray * org.opensearch.common.io.stream.StreamInput => * org.opensearch.core.common.io.stream.StreamInput ** org.opensearch.common.io.stream.StreamOutput => org.opensearch.core.common.io.stream.StreamOutput
* org.opensearch.common.io.stream.Writeable => org.opensearch.core.common.io.stream.Writeable
* org.opensearch.common.io.stream.NotSerializableExceptionWrapper => org.opensearch.core.common.io.stream.NotSerializableExceptionWrapper
* org.opensearch.rest.RestStatus => org.opensearch.core.rest.RestStatus
* org.opensearch.common.ParsingException => org.opensearch.core.common.ParsingException
* org.opensearch.common.bytes.BytesReference => org.opensearch.core.common.bytes.BytesReference
* org.opensearch.common.io.stream.InputStreamStreamInput => org.opensearch.core.common.io.stream.InputStreamStreamInput
* org.opensearch.common.io.stream.OutputStreamStreamOutput => org.opensearch.core.common.io.stream.OutputStreamStreamOutput
* org.opensearch.index.shard.ShardId => org.opensearch.core.index.shard.ShardId* org.opensearch.index.Index => org.opensearch.core.index.Index
* org.opensearch.core.index.IndexNotFoundException => org.opensearch.index.IndexNotFoundException

Validation steps were executed to ensure these changes did not break functionality:
* gradle build was successful. A local build was required due to outdated OpenSearch and job scheduler nightly builds.
* Backward compatibility tests were performed on a two-node 2.9 cluster running some detectors. These detectors continued to produce results on a 3.0 cluster with these updates.
* I can start new detectors on the 3.0 node.
* After shutting down a 2.9 node, the job transfer to the 3.0 node was successful and the job continued to perform as expected.
