No errors when text-block-define is unable to read the file

[ywkaras]

& worse, when a request comes through using that text-block, it doesn't even inject anything!!!

Example:

-rwx------ 1 vinithb users 5 Nov 23 23:41 /home/y/conf/trafficserver/ssl/athenz/mail.backend.jedi.jws.acl_jedi.acl.token.atz.jws.ycpi.yahoo.jwt 

    - text-block-define:
        name: "JWT-mail_cloud-mail.backend.jedi.jws.acl_jedi.acl.token.atz.jws.ycpi.yahoo.jwt"
        path: "/home/y/conf/trafficserver/ssl/athenz/mail.backend.jedi.jws.acl_jedi.acl.token.atz.jws.ycpi.yahoo.jwt"
        duration: "1m" 

Expectation:
Since this is a per-remap plugin, ATS can't fatal but at a minimum, we need an entry in diags/error.log and/or 502 the request.

Found by Yahoo YCPI (Vineeth Bindiganavale). Internal Yahoo issue ID: YTSATS-4083.

This issue was probably seen in 0.4.10 .

Vinith is waiting on this fix. He may start calling somebody Solid Wall of Retired.
