retrying block production

[SurfingNerd]

after x seconds, if a block can't get produced, the network should restart the block production.

or combine with hearthbeat (that happens after 10 min with no block)
if heathbeat is reached a ongoing (maybe stuck) blockproduction is stopped and a new block is started

any transactions of mempool not deleted if a block with them inside isnt successful created so no transaction should be lost

but a possible rare stuck at blockcreation event is countered by restart block

need to clarify this issue.
retrying block production, often referred to "phoenix protocol" (??) should be most of all a diamond-node implementation.
We need to work out if the contracts are part of this change.

i agree to my understanding its a node only thing
no contract is involved as contracts are just executed when a block is generated
this "phoenix protocol" is to avoid most kinds of stuck in a unable to finish block by just restart from scratch after a timeout is reached. maybe some kind of round counter is needed so block contributions and most important block seal mesage fit to the actual atempt
