Rename Martha~ to something like DrsResolver

[BMurri]

Problem:
broadinstitute/cromwell-drs-localizer:develop is moving away from Martha. #391 changes the name of the environment variable used by TES, but it has been suggested that we also change the names in the configuration away from martha to something more generic and to remove the keyvault support.

Solution:
Rename Martha to DrsResolver (in options, configuration, etc.) and remove KeyVaultName and SecretName from MarthaOptions. Extend those changes throughout the deployment/configuration and TES->compute-node ecosystems.
