[hycdong]

What problem does this PR solve?

• fix some unit tests
• update rdsn and update some cmake files

What is changed and how it works?

• fix unit test multi_remove failed
  • rdsn #293 update fail point usage, but not apply new usage to multi_remove, this pr fix it
• fix function test restore and recovery failed
  • pegasus configs: minimize config-server.ini to config.min.ini #370 remove config-server.ini and create config.min.ini, however, restore and recovery function test directly use config-server.ini file name and dynamically modify config in those tests, delete the file will lead to test failed
  • Moreover, config.min.ini format file adding two space characters on the beginning of the line, which leads to modifying config failed, so add \s* to identify space characters in regex for sed command
  • Besides, config.min.ini remove some configs used in those tests, add them to make tests pass
    • add thread pool THREAD_POOL_LOCAL_SERVICE for restore test
    • update worker count to 4 for 'threadpool..default', because recovery test require thread pool THREAD_POOL_META_SERVER has more than one worker
    • add recover_from_replica_server config for recovery test
• update rdsn
  • rdsn #291, add boost::regex in some cmake files

Tips:

• add 'on_travis' option for pegasus function test to skip some time-cosuming function tests. It will skip restore and recovery function test at present
• fix pre-build and zk url
