Metacat

use at least one thread on single-processor machines.

Change the database.maximumConnections property to 100. PostgreSQL's docs says it can handle "a few hundred", and would need to be increased from the default 100 max_connections. For DataONE optimization, we increase max_connections, however there are more processes making connections other than metacat, so I'll reduce metacat's default share.

script for re-applying missing FK constraints on KNB production DB.

include TRACE level debugging for specific classes we want to have performance metrics for.

Add a few logging statemnts for round trip replication metrics.

add trace statements for measuring time to complete SM generation.

new D1 jars:
prevent NPEs from the object format cache when formatId.value is null. This came up during PISCO testing

default replication policy set to 0.

instead of generating SM and ORE maps during dataone configuration/MN registration, moved this all to the replication admin screen where we can target generation for specific nodes. That way it's more controlled as to when and where we generate DataONE required content....

include all EML versions (had been only eml 2.1 for testing)
