(aws-ec2): Extend BastionHostLinux to support CloudFormationInit

[mpvosseller]

Description

It would be helpful if the BastionHostLinux constructor accepted optional CloudFormationInit and ApplyCloudFormationInitOptions arguments to be passed to the ​underlying Instance. This would enable full CloudFormation ​initialization of the instance like installing files.

   ​/**
    ​* Apply the given CloudFormation Init configuration to the instance at startup.
    ​*
    ​* @default - no CloudFormation init
    ​* @stability stable
    ​*/
   ​readonly init?: CloudFormationInit;
   ​/**
    ​* Use the given options for applying CloudFormation Init.
    ​*
    ​* Describes the configsets to use and the timeout to wait
    ​*
    ​* @default - default options
    ​* @stability stable
    ​*/
   ​readonly initOptions?: ApplyCloudFormationInitOptions;

Use Case

In my case I want to install files and run a command at initialization time.

Proposed Solution

Add two optional arguments init and initOptions to BastionHostLinuxProps. In BastionHostLinux pass these arguments to the Instance constructor when creating the underlying instance.

Appreciate the work on this so far, are there plans to support cfn-hup?

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-hup.html

Right now the generated UserData doesn't configure cfn-hup so any updates to the AWS::CloudFormation::Init resource aren't picked up without a host replacement.
