[Remote Store] Incorrect Recovery Type shown in _cat/recovery API when remote store is enabled.

[Rishikesh1159]

Describe the bug
With remote store enabled when a new replica is added to the cluster, the recovery type should be remote_store instead it gives peer as recovery type.

$ curl localhost:9200/_cat/recovery?v
index shard time type    stage source_host  source_node target_host  target_node repository snapshot files files_recovered files_percent files_total bytes bytes_recovered bytes_percent bytes_total translog_ops translog_ops_recovered translog_ops_percent
so  0   143ms empty_store done n/a      n/a     node-ip node-1   n/a    n/a   0   0        0.0%     0      0   0        0.0%     0      0      0           100.0%
so  0   4.7m peer    done node-ip node-1   node-ip node-3   n/a    n/a   1   1        100.0%    169     3776 3776      100.0%    36711602919 0      0           100.0%

To Reproduce
-> Create a index with some data.
-> Add new replica to the index
-> Call _cat/recovery and check the output.

Expected behavior
The recovery type must be remote_store not peer

We decided on further fine tuning statuses to add replica recovery to be more specific so as to not tie recovery to the source but rather talk about what kind of recovery it stands for.
