Add denyRegex support for import-alias-naming rule

[denisvmedia]

This PR provides an extension to the existing import-alias-naming rule. While it preserves the backwards compatible configuration, with which it is possible to define an allow regex pattern for import aliases, this PR brings a way to configure any or both pattern types: allowRegex and/or denyRegex. This brings two types of configuration:

1. The original one, allow pattern:

   # the original one, allow pattern
   [rule.import-alias-naming]
     arguments = ["^[a-z][a-z0-9]{0,}$"]

2. The new one, both allow and deny patterns:

   [rule.import-alias-naming]
     arguments = [ { allowRegex = "^[a-z][a-z0-9]{0,}$", denyRegex = '^v\d+$' } ]

Closes #924.
