Feature Request: Support for Security Groups in FSX Lustre Settings

**Required Info:**
- AWS ParallelCluster version 3.7.2

I am blocked from using the Parallel Cluster CLI in enterprise-provided AWS accounts and in most of the government-provided AWS accounts I have encountered due to the creation of the FSX Cluster Security Group and Security Group Rules that are part of the FSX Lustre Cluster deployment. Due to security restrictions in place on these types of accounts, account-level IAM users are blocked from creating their our own Security Groups and Rules. Instead, a set of standard groups/rules are provided for each account.

In order to enable use of the Parallel Cluster CLI within enterprise and government AWS environments, can we please have the option to configure existing Security Groups to be used in the FSX Lustre Cluster deployment over forcing the creation of a new group with no option to add one?

An example config snippet below...

```
SharedStorage:
MountDir: /workspace
Name: fsx-workspace
StorageType: FsxLustre
FsxLustreSettings:
StorageCapacity: 1200
ImportedFileChunkSize: 1024
ExportPath: s3://pcluster-training-workspace
ImportPath: s3://pcluster-training-workspace
SecurityGroupIds:
- sg-xxxxx
- sg-xxxxx
```

Start by locating the configuration and deployment handling for FsxLustreSettings and the proposed SecurityGroupIds field. Trace how FSx Lustre security groups and rules are currently created, then verify that existing groups can be configured and used without forcing new group creation.
