Accept filters multiple times in history list. (#3979)

ListEvaluationHistory RPC accepts multiple entries for string-like
filters, e.g. evaluation statuses, profile names, etc. While minder
CLI internally manages those filters as slices, viper is not
configured to accept repeated options.

This change makes it possible to provide `--profile-name`,
`--entity-name`, `--entity-type`, `--eval-status`,
`--remediation-status`, and `--alert-status` options multiple times
with different values, all of which will eventually be passed to the
backend as filters.

Fixes #3978
