Implementing pagination for _cat/indices API (#14718)

[gargharsh3134]

• Implementing pagination for _cat/indices

Description

[Describe what this change achieves]

Backporting #14718

Additionally also fixed the RestHandlerWrapper, which was backported as part of this #16161 but since this PR is getting merged later in 2.x, added this explicitly:

@Override
        public boolean isActionPaginated() {
            return delegate.isActionPaginated();
        }
