PH: Change default transaction generator trx expiration

[heifner]

The transaction generator, used in performance testing, default transaction expiration was set to 60 minutes. 60 minutes is the also the default maximum transaction expiration limit. Since the comparison is <= pending_block_time this can fail.

Changed the default to 30 minutes which is more than enough. Seems, any performance test that takes 30 minutes to get a transaction to execute should be considered a failure.

spring/libraries/chain/controller.cpp

Line 5840 in 8cc52d9

EOS_ASSERT( trx.expiration.to_time_point() <= pending_block_time() + fc::seconds(chain_configuration.max_transaction_lifetime),

Resolves #1093
