Enforce Rate Limit for Batch Submission

[kzscisoft]

Problem Statement

There is a 20,000 run limit for batch runs submission, currently there is no reference to this within its implementation within the LLAPI.

Solution

Either add validation to ensure that the number of submissions in a request does not exceed this threshold, or carry out the multiple submissions.

Alternatives Considered

Enforce only within the CLI, however this is not the best solution.

Additional Context

Needed for submission of large volumes of runs as part of the "loadSim" feature.
