Support for AS Path filters

[HumlePung]

Is your feature request related to a problem? Please describe.
To document and use this to update configuration, this should be nice to have in there.

Describe the solution you'd like
Add AS Path filter option, need to support to put in Regex, can be a text field example. As long as it can be used in the API.

Describe alternatives you've considered
This is can be done with just json in the object, but is not that easy for everyone.

Additional context
Example for an AS Path filter:
as-path-filter ASPF-ALREION-IMPORT index 10 permit ^1299.*
