App installation on client side

[MatejVukosav]

Instead of the node making assumptions on the application registry and contract (currently fetching from NEAR testnet on a pre-defined contract calimero-package-manager.testnet), the new design of application install from #461 allows the node to consume and store streams of arbitrary data.

The new model for app installation should be:

• From the client side, armed with knowledge of the user's registry source (NEAR mainnet / testnet or wherever else) and the registry contract address, the client retrieves the URL for the application.
• The client makes a request to the node, opening up a stream for a blob upload.
• The client makes a request to the blob URL, piping it's response stream to the node.
• The node responds with a blob ID.
• The client makes a request to the node once more, to create an application record, passing it the BlobID and other metadata like a source URL.
• The node responds with an ApplicationID == BlobID
• The client can now create contexts using the ApplicationID

Notable changes in client:

• frontend : get stream from ipfs and send it to node

Blocked on #461

Taking 2 PR's closed into the consideration, is there still something pending from your side or should we close this issue ? @miraclx
