Add an option to protected branches to add writing deploy keys to the whitelist for pushing.
Please note this is technically a breaking change: previously if the owner of a repository was on the whitelist then any writing deploy key was effectively on the whitelist. This option will now need to be set if that is desired.
Closes #8472
Details:
* Allow Protected Branches to Whitelist Deploy Keys
* Add migration
* Ensure that IsDeployKey is set to false on the http pushes
* add not null default false
* Allow committing / adding empty files from the web ui (#8420)

This PR fixes #7598 by providing a configurable way of signing commits across the Gitea instance. Per repository configurability and import/generation of trusted secure keys is not provided by this PR - from a security PoV that's probably impossible to do properly. Similarly web-signing, that is asking the user to sign something, is not implemented - this could be done at a later stage however.
## Features
- [x] If commit.gpgsign is set in .gitconfig sign commits and files created through repofiles. (merges should already have been signed.)
- [x] Verify commits signed with the default gpg as valid
- [x] Signer, Committer and Author can all be different
- [x] Allow signer to be arbitrarily different - We still require the key to have an activated email on Gitea. A more complete implementation would be to use a keyserver and mark external-or-unactivated with an "unknown" trust level icon.
- [x] Add a signing-key.gpg endpoint to get the default gpg pub key if available
- Rather than add a fake web-flow user I've added this as an endpoint on /api/v1/signing-key.gpg
- [x] Try to match the default key with a user on gitea - this is done at verification time
- [x] Make things configurable?
- app.ini configuration done
- [x] when checking commits are signed need to check if they're actually verifiable too
- [x] Add documentation
I have decided that adjusting the docker to create a default gpg key is not the correct thing to do and therefore have not implemented this.

When different prefixes are supplied, the result is the intersection.
For example,
"author:alice author:bob"
=> the result is all commits authored by Alice OR Bob
"hello committer:alice"
=> the result is all commits committed by Alice AND has the keyword
'hello' in the message.
Note that there should NOT have any space after the colon(:) of the prefix.
For example,
"author:bill" => correct
"author: bill" => wrong

Include the current CustomPath location in the admin section and also
display GITEA_WORK_DIR and/or GITEA_CUSTOM env var if they are set.
Right now there is no easy way to see this information, and if you try
and help most users they won't be able to tell you anything about these
values -- just that their custom template isn't working, files aren't in
the right place, etc... Now you can see all paths and if they were set
by ENV or not.

1. A key can either be an ssh user key or a deploy key. It cannot be both.
2. If a key is a user key - it can only be associated with one user.
3. If a key is a deploy key - it can be used in multiple repositories and the permissions it has on those repositories can be different.
4. If a repository is deleted, its deploy keys must be deleted too.
We currently don't enforce any of this and multiple repositories access with different permissions doesn't work at all. This PR enforces the following constraints:
- [x] You should not be able to add the same user key as another user
- [x] You should not be able to add a ssh user key which is being used as a deploy key
- [x] You should not be able to add a ssh deploy key which is being used as a user key
- [x] If you add an ssh deploy key to another repository you should be able to use it in different modes without losing the ability to use it in the other mode.
- [x] If you delete a repository you must delete all its deploy keys.
