In Replication panel warn that not all replications may be displayed.

Overview

In the "Replicator DB Activity" tab of the Replication panel
add the message "Up to about 100 replications are displayed."

When there are many _replicator documents, users are puzzled
when some replications do not show up in the
Replicator DB Activity panel of the Replication panel.

In my test using Cloudant I found that the number of replications
displayed in the Replicator DB Activity tab of the Replication panel was 99.
That must be because we get 100 _replicator documents at:
https://github.com/apache/couchdb-fauxton/blob/main/app/addons/replication/api.js#L314

const url = Helpers.getServerUrl('/_replicator/_all_docs?include_docs=true&limit=100');

And then at https://github.com/apache/couchdb-fauxton/blob/main/app/addons/replication/api.js#L321
we filter out all the design documents:

return parseReplicationDocs(res.rows.filter(row => row.id.indexOf("_design/") === -1));

And in Cloudant the _replicator database is created with a
design document _design/_replicator.
So of the 100 _replicator documents that were retrieved,
one was filtered out, leaving 99 replications to be displayed
in the "Replicator DB Activity" tab of the Replication panel.

When I tried the same thing with Apache CouchDB,
the _replicator document did not contain any design documents,
so 100 replications were displayed.
