add script for single issuer and single holder ipex

[lenkan]

Adding reference script for issuing a credential using a single issuer and a single holder. Includes updates to ipex().grant() from @kentbull.

Original post:

Referring to the discussion from discord today. Here is a script that performs credential issuance with IPEX grant + admit with a single issuer and a single holder.

This script stops at line L266 printing "No credentials yet..." because the holder never gets any credentials from its agent.

Do you have any pointers to what I am doing wrong here? I believe I am missing a crucial step in either the "issueCredential" or "admitCredential" function.

Thanks @pfeairheller for the updates and adding the /ipex/admit to KERIA. I have tried this again by porting the "submitAdmit" function to here.

• Client for new ipex admit API and updated issue-ecr.sh to work with IPEX signifypy#93
• WebOfTrust/keria@f80d976

However, KERIA now becomes unresponsive after posting the /ipex/admit message. After debugging I found that execution stops in the Admitter when calling "parseOne" on the "iss" embed: WebOfTrust/keria@f80d976#diff-a169faf61f8a8fdf3be4d9d2a164f646003d0f5203efb18f599f4b59393327efR527

parser.parseOne simply never returns. It gets stuck in the infinite loop here: https://github.com/WebOfTrust/keripy/blob/6ab521ec83f1bfd67882199fea4c5f45d91304c4/src/keri/core/parsing.py#L418

Do you have any idea as to what could cause the parser from getting stuck in an infinite loop.

I am a bit worried that these background tasks can make the API unresponsive. I thought maybe the Doers was a way to prevent that?
