Create govtool metadata submission service

[MSzalowski]

What

In order to integrate with the new services architecture extract metadata creation functionality into the separate package.

How

Metadata creation service should work in both ways:
Provider:

<MetadataProvider>{children}</MetadataProvider>

and usage with hooks

const { validate, initialize } = useMetadata();

And service:

const metadataService = new MetadataService(...config)

• Metadata service should follow CIP-108 standard.
• Metadata service should provide fields validation described in the above standard.
• Metadata service should build jsonld as an output.
• Metadata service should not use CSL in v1 hence, no on-chain data are to be applicable on first delivery.

@pmbinapps Why is that being blocked?

[MSzalowski]

The issue has been blocked due to failed test-env deployment.

[pmbinapps]

Unable to verify Registration as Drep and Submitting new GA due to:

DRep registration - Registration hang up after providing json file and confirming

GA - entering to GA submit wizard causes error 500 (dev) or black screen (test) and error 405
#1015

[pmbinapps]

UPDATE: not valid checks, related to Wrapper.

Adding meta data:
OK for dRep
OK for Info GA

TO CHECK: Rest of GA types

[MSzalowski]

That is to be moved to the https://github.com/IntersectMBO/govtool-assembly

This package is not testable at the moment.
