Add bucket retention policy for sentinel-input-files bucket.

[sharkinsspatial]

As completed in #281 the sentinel-input-files bucket should also have a retention policy. For this bucket it should be 6 months.

@sharkinsspatial, shall we set the retention to 30 days for the mcp-dev-viirs env and 6 months for the mcp-production-viirs env?

I have manually created these lifecycle rules:

• hls-mcp-development-viirs-sentinel-input-files: expire objects after 15 days
• hls-mcp-production-viirs-sentinel-input-files: expire objects after 120 days (we can dial it down further in January)

I'll add them to the CDK stack after the holidays.

I wanted to add a note here that since these buckets have replication rules enabled, both these actions need to be checked while creating the lifecycle rule

• Expire current versions of objects
• Permanently delete noncurrent versions of objects

The first one (expire) simply creates a delete marker but will not delete the noncurrent objects.
I edited the lifecycle rules with this change for the buckets listed above and we saw the expected drop in bucket volume over last few days.
