Fix Undefined constant "STDIN" error caused when SetUpTenantDatabase listener is called in production apps.

Add check to get redirect url from request; if redirect_url is present in query string

Allow custom user defined tenant middleware groups; allowing multiple values in config/tenancy.php under routes.middleware.groups

Update resolveTenant method to check if passed value is instance of tenant model as defined in config

• Added check to allow user defined redirect route and associated params to be pulled from request; using keys redirect_to and redirect_params

Enable non-tenant tasks to be run in the middle of tenant tasks

Changes to Tenancy class:

• Added setTenant method to provide a quick way to set a tenant in Manager
• Added runNonTenantTask method to enable running of non-tenant tasks in the middle of tenant tasks before resuming with tenant tasks

Add clearTenant method to unset the tenant from Manager

Add check to determine if tenant is set in Manager before resolving the database connection name for a Model using ForTenants trait via MultiDatabaseDriver driver

This enables a single model to be used for tenant based logic and non-tenant based logic

• Refactored resolveTenant method to factor in non-subdomain based route check
• Updated resolveTenant implementation in SetTenant middleware to factor in the changes

Enable non-tenant subdomains to use tenant middleware alongside the package's subdomain feature;

The tenant is resolved from the store defined in config (ie, cookie, cache, session, DB)
