Allow additional settings for GSSAPI in Vhost

[tuxmea]

Adding config items:

• allowedmech
• authname
• authtype
• basicauth

@tuxmea Sorry for the wait on review. Anyway this change look's good to me but could you also update the relevant documentation linked below? Would be sad if you put in a great change like this and nobody could find it:

• puppetlabs-apache/manifests/vhost.pp

  Line 1507 in 488a1f5

  # @param gssapi

@tuxmea Sorry to come back but while reviewing other prs I noticed that a similar change had been pushed up by another contributor that contains part of the functionality that you yourself have added. Just felt I should alert you as depending on which PR is merged first you may need to rebase your work.
Have placed a similar comment on the other PR, linked below:

• mod_auth_gssapi: Add support for every configuration directive #2214

[david22swan]

In relation to the comment above, have discovered two more PRs that are adding similar functionality to this, one of which was in a good enough state to be merged:

• mod_auth_gssapi: Add support for GssapiBasicAuth. #2212

And another which will require some more work:

• Added in basic auth and no-negotiate options #2204

@tuxmea Hey, just giving an update but on of the PRs I previously mentioned has been merged in so that now allowedmech and basicauth are already included as options.
If you could rebase your code and add the documentation I had previously mentioned however I would be happy to merge this in and get the remaining two options you have tried to add into the codebase.

There is now a merge conflict. While some more parameters have been added, at least AuthName and AuthType have not so there's still value in this PR. Please rebase to resolve the conflicts.

@david22swan @ekohl many thanks for your feedback. PR is rebased and ready to get merged. I also updated the documentation in manifests/vhost.pp

The spec failure looks odd. I'm not sure how this PR could have caused that and we also see it in nightly: https://github.com/puppetlabs/puppetlabs-apache/runs/7381259870?check_suite_focus=true (that said, it is still odd that in Puppet 6 it fails, but doesn't in 7).
