Handle exception for the updation of a replication rule

[skumarp7]

Description

This PR handles the exception handling for updation of a replication rule.

Earlier behavior:

First hit of the replication rule:

curl -Method POST -Uri "http://localhost:9201/_plugins/_replication/_autofollow?pretty"  -H @{'Content-Type' = 'application/json'} -body '{"leader_alias":"leader", "name": "test3", "
pattern":"test*"}'

StatusCode        : 200
StatusDescription : OK
Content           : {
                      "acknowledged" : true
                    }

Second hit of the same Replication rule:

curl -Method POST -Uri "http://localhost:9201/_plugins/_replication/_autofollow?pretty"  -H @{'Content-Type' = 'application/json'} -body '{"leader_alias":"leader", "name": "test3", "
pattern":"test*"}'

StatusCode        : 200
StatusDescription : OK
Content           : {
                      "acknowledged" : true
                    }

New behavior: First hit of the replication rule:

curl -Method POST -Uri "http://localhost:9201/_plugins/_replication/_autofollow?pretty"  -H @{'Content-Type' = 'application/json'} -body '{"leader_alias":"leader", "name": "test3", "
pattern":"test*"}'

StatusCode        : 200
StatusDescription : OK
Content           : {
                      "acknowledged" : true
                    }

Second hit of the Replication rule:

curl -Method POST -Uri "http://localhost:9201/_plugins/_replication/_autofollow?pretty"  -H @{'Content-Type' = 'application/json'} -body '{"leader_alias":"leader", "name": "test3", "
pattern":"log*"}' 

curl : { "error" : { "root_cause" : [ { "type" : "resource_already_exists_exception", "reason" : "task with id {autofollow:leader:test3} already exist" } ], "type" : "exception", "reason" : "Exisiting Autofollow replication     
    rule cannot be updated", "caused_by" : { "type" : "resource_already_exists_exception", "reason" : "task with id {autofollow:leader:test3} already exist" } }, "status" : 500 }

Hi @ankitkala & @monusingh-1 ,

Please provide feedback :)

Hi @ankitkala @monusingh-1 and other maintainers,

I could see the integTest is failing for the below test case -

org.opensearch.replication.integ.rest.StartReplicationIT > test operations are fetched from lucene when leader is in mixed mode FAILED
    org.opensearch.client.ResponseException: method [PUT], host [http://[::1]:34485], URI [_cluster/settings], status line [HTTP/1.1 400 Bad Request]

I was able to find a PR which involves the exclusion of this test case in integTestRemote Task but not in integTest.

https://github.com/opensearch-project/cross-cluster-replication/pull/1379

I have for now excluded this particular test case from the integTest. Let me know if any other plan to fix this test case?

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.x 2.x
# Navigate to the new working tree
cd .worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-1405-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 2da20341107bfe707487d93d271df70aed31356d
# Push it to GitHub
git push --set-upstream origin backport/backport-1405-to-2.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-1405-to-2.x.
