Adds SetLimitsCustomizer for centos/rhel
I tested this with the catalog item:
```
brooklyn.catalog:
id: my-nginx-node
itemType: entity
item:
type: org.apache.brooklyn.entity.proxy.nginx.NginxController
brooklyn.parameters:
- name: ulimits
type: java.util.List
description: |
Contents to add to the limits config file
default:
- "* soft nofile 16384"
- "* hard nofile 16384"
- "* soft nproc 16384"
- "* hard nproc 16384"
brooklyn.config:
provisioning.properties:
machineCustomizers:
- $brooklyn:object:
type: io.cloudsoft.amp.cluster.customizer.SetLimitsCustomizer
brooklyn.config:
contents: $brooklyn:config("ulimits")
nginx.sticky: false
install.version: 1.12.1
```
I deployed this to aws eu-west-1 using `imageId: eu-west-1/ami-5f76b626`
(i.e. the official centos marketplace image).
I then checked that the nginx process had the correct "max processes" and
"max open files":
```
ps aux | grep nginx
aled 14120 0.0 0.0 43764 1672 ? Ss 16:26 0:00 nginx:
master process ./sbin/nginx -p

```
I also deployed a similar nginx without the customizer, and confirmed these
had:
```
Max processes 4096 14996

Max open files 1024 4096 files
```
