Terraform-compliance

* Fixed a problem where `integer` and `boolean` values where causing comparison problems on `When its <key> contains <value`>. ([231](https://github.com/eerkunt/terraform-compliance/issues/231))
* Fixed a problem where `boolean` values where causing a problem on `Then its <key> <condition> be <value>`. ([232](https://github.com/eerkunt/terraform-compliance/issues/232))
* Improved `When its <key> is <value>` steps for `reference` usage where you can provide a `key/value` check like `When its security_group_id reference is something`. ([234](https://github.com/eerkunt/terraform-compliance/issues/234))
* Improved `When its <key> is not <value>` steps for `reference` usage where you can provide a `key/value` check like `When its security_group_id reference is not something`. ([234](https://github.com/eerkunt/terraform-compliance/issues/234))

* Improved `When its <key> contains <value>` step where `<value>` can have space in it. ([docs](https://terraform-compliance.com/pages/bdd-references/when.html#)) ([226](https://github.com/eerkunt/terraform-compliance/issues/226))

* Fixed a problem where `Then its <key> is <value>` step was not searching for "exact" matches. ([225](https://github.com/eerkunt/terraform-compliance/issues/225))

* Fixed a problem where int, bool and float types was not properly filtered and matched.
* Fixed a problem where filtering functions does not work properly.

* Fixed a problem where a property within the terraform plan fails to get parsed if it is list of lists. ([221](https://github.com/eerkunt/terraform-compliance/issues/221))

* Fixed a problem where tags are not recognised on Auto-Scaling Groups due to different key/pair structure within the terraform. ([208](https://github.com/eerkunt/terraform-compliance/issues/208))
