fix(DataMapper): Cannot resolve metadata once route ID is changed

[igarashitm]

Fixes: KaotoIO/kaoto#1702

Just use 32bit pseudo random instead of UUID

It looks good to me, I tried it locally and the previous ID format is preserved as well.

For completeness, this is how the new ID looks like: kaoto-datamapper-4a9490ba.

That being said, could it be possible to add a simple test checking that when using the getHexaDecimalRandomId function, we get a string with the given format? I'm not sure whether we have the real implementation during the tests though.

Ok, I checked and it looks like we don't have the real implementation available, but we can see the existing tests and apply them to the new function, mostly to document what's the intended format.

As an example, we could add this test for the getCamelRandomId function that we were missing.

  it('should fulfill the format', () => {
    expect(getCamelRandomId('route')).toMatch(/route-\d{4}/);
  });
