fix(FEC-8739): block action is not fired from OTT provider

[OrenMe]

Description of the Changes

OTT BE rule action enum is a string equal to BLOCK while in OVP it is an int equal to 1.
We are currently using a base enum, which is incorrect as the enums are different, so need to separate the enum.
I also moved the base provider parser utility functions to more appropriate places, as having a base with shared enums between providers is not manageable.
