Subject: bmcweb: Show exception what() before exiting

Although exceptions should not happen in bmcweb, the underlying Crow
code sometimes throws, and so do bugs caused by accidental usage of
functions that throw.

Adding e.what() output when std::exception is thrown.

Tested: Accidentally tested more often than I would care to admit....
