secure-systems-lab/securesystemslib#288 changes the key generation
interface functions in such a way that it is clear if a call opens
a blocking prompt, or writes the key unencrypted. To do this two
functions are added per key type:
- `generate_and_write_*_keypair_with_prompt`
- `generate_and_write_unencrypted_*_keypair`
The default `generate_and_write_*_keypair` function now only allows
encrypted keys and only using a passed password. This respects the
principle of secure defaults and least surprise.
sslib#288 furthermore adds a protected
`_generate_and_write_*_keypair`, which is not exposed publicly
because it does not encrypt by default, but is more flexible and
thus convenient e.g. to consume all arguments from a key generation
command line tool such as 'repo.py'.
This commit adds the new public functions to the tuf namespace and
adopts their usage accordingly.
NOTE regarding repo.py:
This commit does not fix any problematic password behavior of
'repo.py' like default passwords, etc. (see #881). It only adopts
the sslib#288 changes to maintain the current behvior, plus
removing one glaringly obsolete password prompt.
NOTE regarding key import:
The securesystemslib private key import functions were also changed
to no longer auto-prompt for decryption passwords , TUF, however,
only exposes custom wrappers (see repository_lib) that do
auto-prompt. sslib#288 changes to the prompt texts are nevertheless
propagated to tuf and reflected in this commit.

One of the created target files has its file permissions encoded in the
targets metadata via the custom attribute of the add_target() function.
On Linux-based OS the umask value of the environment the script is run
in can result in different octal permissions for the created file, i.e.
on Fedora the default umask is 0002 (default permissions 664) whereas
on Debian/Ubuntu the default umask is 0022 (default permissions 644).
Explicitly chown 'file1' to octal permissions 644 so that the generated
data has the same custom attributes for targets regardless of which
Linux host they are generated on.

Update unit tests for download.py, repository_lib.py, repository_tool.py, and updater.py.
Re-generate repository data so that compressed metadata may be tested.
Added two switches to the generate script:
-k (or --keys), which forces the creation of new keys.
-d (or --dry-run), which skips the actual writing or copying phases
The second option might be useful in the future, and helped me debug the
optparse module, so I left it there.
