Support Log Reading

[chenww05]

As smbd1368 suggested, we should be able to support reading logs from data like Intel:
For example, in The Intel Net Batch logs, the data is as follows:

• job ID (anonymized)
• group (anonymized)
• user (anonymized)
• command (anonymized)
• submit time (local timestamp)
• start time (local timestamp)
• end time (local timestamp)
• exit status
• suspend time (seconds)
• wall time (seconds)
• user CPU time (seconds total for all threads)
• system CPU time (seconds total for all threads)
• max RSS (4KB pages)
• max VM (4KB pages)
• machine ID (anonymized)
• iteration number
• iteration submit time (local timestamp)
• memory (GB total for all threads)
• cores.
