Refactoring: Extract helper methods in apex test to utils class

Add new file ApexTestUtils.java
Any test, in this package, derived from ApexE2EBaseHostTest will have a
utils field that can be used to access the extracted methods.

Also made some useful constants protected so that they can be accessed
by derived tests.

Test: atest apex_e2e_tests
