Accept protocol v2 server options on fetch and ls-refs requests
In protocol v2, a command request can be followed by server options
(lines like "agent=<>" and "server-option=<>"), but current code
doesn't accept those lines.
Advertise the "server-option" capability, parse the lines and add
them to the request objects.
Other code in JGit can see this options and act accordingly via the
protocol v2 hooks.
This should not require any change in the client side.

ssh: Prefer algorithms of the known host keys
JSch prefers ssh-rsa key type. When the remote server supports ssh-rsa
key type then this key type will be used even if the known_hosts file
contains a host key for that host, but with different key type.
This caused an unexpected UnknownHostKey error.
To fix the issue first scan the known_hosts, the HostKeyRepository in
JSch API, for any already existing host keys for the target host and
modify the default session settings to prefer their algorithms. However,
do this only if there is no HostKeyAlgorithms setting active.

UploadPack: Use request instead of field for depth
One more step in removing state from UploadPack, using the request
object instead.
Unfortunately, hooks get from UploadPack information about the current

This kills half the benefit of using a request object vs fields, but
at least we still get better modularity.
