Add the test for the cache configuration (#730)

* Add information to check the cache sdk version and the working sdk version

* Set the log level to info for test

* Add environment variable for error injection test

* format the code for lint check

* Add information to show the ENGION OPTIONS set

* Make it recompile when cache version mismatch

* Remote the environment for error simulator to make it set by environment variable

* Add error injector for temporarily test

* Fix the problem when there's not the error injection config file

* Move the error injector to the odla_CreateComputation to make sure it will be called for each inference request

* Add try catch to computation create and init

* make the error handling code at one place

* Use config file setting for batch per step when it's inconsistent with ODLA set

* set the log level when error injector used

* pass the error code to caller

* Make sdk version mismatch cache recompile when error injector set

* Make the popart log level take POPART_LOG_LEVEL firstly

* change format to pass lint
