[dpdk-dev] [PATCH v4 2/2] test/metrics: fix metrics autotest failure

[Harman Kalra <hkalra@marvell.com>]

Issue is observed while running 'metrics_autotest' continuously
without quiting. During first execution all test cases pass but
second run onwards first test case fails as library is already
initialized.

To resolve, introduced a new API to deinitialise the library
after all test cases are executed.

Fixes: cd3804242901 ("test/metrics: add unit tests for metrics library")
