[pbs-devel] [PATCH v3 proxmox-backup 1/4] api-types: implement dedicated api type for match patterns

[Christian Ebner <c.ebner@proxmox.com>]

Introduces a dedicated api type `PathPattern` and the corresponding
format and input validation schema. Further, add a `PathPatterns`
type for collections of path patterns and implement required traits
to be able to replace currently defined api parameters.

In preparation for using this common api type for all api endpoints
exposing a match pattern parameter.
