Change conversion to toStringShort() instead of toBase58String() - as done for H2 Cash Selection.
Fix withIssuerRefs case - iterate via list of IssuerRefs and setBytes instead of setArray of BYTEA.
Add test for Cash Selection with issuerRef.
Since we are running web-server and different handling methods will be called from
different threads, it is more appropriate to use concurrent data structures
for exchanging information between threads.
Prior to this change I observed the following exception which is likely to be due `certPaths` not synchronized between threads:
```

Packages re-jig was meant to reduce the size of the jars that are being produced by the
node driver. E.g. previously `MessageState` was in package `net.corda` which resulted in jar file
of around 2MB to be created. Same for `NodeStatePersistenceTests` which was in `net.corda.node`
* Improve logging for NetworkMap requests
* Allow interrupt in polling if the process started successfully
* Put `advertiseNewParameters` back
* Additional log line to indicate when all the nodes are started
* Improve logging and use concurrent map since it is updated from multiple threads
* Change NetworkMap response validity duration and rename parameter accordingly
* Changes following code review from @shamsasari
* Instantiating the contract class should be part of contract verification. We should not instantiate it while building LedgerTransaction.
* Also catch any exceptions from instantiating the contract.
