EPIC: OAuth2 User Accounts

[jsync-swirlds]

Goal

Create user accounts when HBAR transferred to the Block Node payment account (depends on state management).

Intention

When an Hedera account sends at least (n) HBAR (configurable, large enough to ignore "dusting"), create an account on the Block Node for that Hedera account (just AccountID, Key, local_balance). When any existing account is updated with a modified Key, or transfers HBAR to the Block Node, update the local account accordingly (changing Key or increasing local_balance by amount transferred). Provide account data to the OAuth2 provider when requested for a particular accountID, so that provider can validate signature and include available balance in the OAuth2 token.
