In Manage Jenkins > Amazon EC2 Container Service Cloud > ECS Cluster, the drop down only shows up to 100 ecs clusters.

In our infrastructure, we have about 260 ecs clusters and noticed that Jenkins ECS plugin will only show up to 100 ecs cluster which prevents selecting the correct ecs cluster. The plugin might need to incorporate disable pagination by providing the --no-paginate argument so that it displays over 100 ecs clusters.

Tested:
1. deploying ecs cluster to our region with 260 ecs cluster does not show up in jenkins ecs cluster drop-down.

2. deploying ecs cluster to our region with less than 20 ecs cluster shows up in the jenkins ecs cluster drop-down.

3. tested on two separate jenkins servers v2.7.4 and both will only show up to 100 ecs clusters
