FIPS support without BouncyCastle

[tristantarrant]

Is your enhancement related to a problem? Please describe

Currently, in order to use EC keys, the code checks for the BouncyCastle provider. Because of redistribution limitations with the BC FIPS jars, the client should also allow using a JDK configured to use the NSS-backed security provider (this, for example, is automatically enabled on RHEL/CentOS in FIPS mode).

Describe the solution you'd like

The code should test to see if EC keys can be handled directly by the JDK before resorting to other strategies (e.g. BouncyCastle).

Describe alternatives you've considered
