Add body parser limit option to app

[burzaszsolt]

We get en error in the UMC api about a request payload being too large. This can be solved by increasing the body limit for json body parser.

👋 Hi!

Sorry for interrupting your PR workflow, but we need your help!

We're busy updating the Infinitas Service Catalog so it contais a list of all the services we have at Infinitas and make them easily discoverable for everyone. You can find the catalog here in Notion.

The thing we're asking all repository contributors is to add a bit of metadata to your repository by adding a catalog-info.yaml to the root of each repository that we automatically index each night.

If you want to take a look at a working implementation, please check the eCommerce repo

Once the catalog file is added to the repo we'll promise to stop reminding you when creating new PR's.

Might you need any further assistance feel free to reach out to Clifton, Henk or Jerome.

And remember:
