Add memory to conditional options for all launch types

[ginman86]

This PR adds the memory parameter to the conditional options. This parameter can be set in either fargate or ec2 launch types and should always be included in the copied task definition if it is present.

[ginman86]

This parameter needs to be included in order for it to be set when automatically generating new task-definition versions. Otherwise it will revert to the default, breaking the deploy for any task definitions that need specific memory settings.

@ginman86 this change looks pretty simple, but it's throwing errors for me:

Parameter validation failed:
Invalid type for parameter memory, value: None, type: <class 'NoneType'>, valid types: <class 'str'>

What version of awscli are you using for that option? I'm not on the latest, but I am on the latest for Ubuntu 20.04:

> aws --version
aws-cli/1.18.69 Python/3.8.5 Linux/5.8.0-44-generic botocore/1.16.19

Bump. Need this fix. Getting An error occurred (ClientException) when calling the RegisterTaskDefinition operation: Invalid setting for container 'my-container'. At least one of 'memory' or 'memoryReservation' must be specified every time deploying to ECS's EC2 instance.

Given the age of this PR and that it has conflicts, I'm going to close it out. If you still want to pursue this, please submit a new PR based on the latest code.
