Fails to create database tables

Problem/Motivation

In some cases ie. installations with database prefixes or via drush cim instead of drush en regex_redirect, the Regex Redirect module fails to create its required prefix_regex_redirect or regex_redirect tables.

Steps to reproduce

1. Set up multisite with database prefixes
2. Enable Regex Redirect via drush cim -y (config import) instead of drush en regex_redirect
3. Access a prefixed site and try to use Regex Redirect functionality
4. Get error: SQLSTATE[42P01]: Undefined table: relation "prefix_regex_redirect" does not exist

Proposed resolution

Add proper hook_install() and update hooks to regex_redirect.install that explicitly install entity schema using EntityDefinitionUpdateManager.

Remaining tasks

User interface changes

API changes

Data model changes
